1. Introduction to Direction Sense
Direction Sense is one of the most consistently scoring topics in the Reasoning section of SSC and RRB exams. Almost every paper — CGL, CHSL, MTS, GD, NTPC or Group D — carries at least one to three questions from this single topic. The good news is that the underlying idea is simple: track where a person ends up after a series of movements and turns. The challenge is doing this quickly and accurately under time pressure, without a diagram in front of you.
1.1 The Compass and the Eight Directions
A standard compass has four main directions — North, South, East and West — and four intermediate (diagonal) directions formed exactly halfway between two main directions — North-East, South-East, South-West and North-West. In almost all SSC/RRB questions, unless the question states otherwise, the following convention is used:
- Facing "up" the page = facing North.
- Facing "down" the page = facing South.
- Facing "right" on the page = facing East.
- Facing "left" on the page = facing West.
This is exactly how a geographical map is drawn — North at the top, East on the right. Keep this fixed in your mind before you read a single line of the question; almost every error in this topic starts from getting this orientation wrong.
Quick Reference: The Eight Directions
| Direction | Abbreviation | Compass Angle (from North, clockwise) | Opposite Direction |
|---|---|---|---|
| North | N | 0° | South |
| North-East | NE | 45° | South-West |
| East | E | 90° | West |
| South-East | SE | 135° | North-West |
| South | S | 180° | North |
| South-West | SW | 225° | North-East |
| West | W | 270° | East |
| North-West | NW | 315° | South-East |
1.2 Left and Right Turns Relative to Facing Direction
"Left" and "right" are always relative to the direction the person is currently facing — not relative to the reader or the page. If a person is facing East and turns "left", they now face North, because North is to the left hand of someone looking East. This single idea trips up more students than any other in this chapter, so it deserves a permanent reference table.
Quick Reference: Turn Rules
| Facing | Left turn (90°) → | Right turn (90°) → | 180° turn (about-turn) → |
|---|---|---|---|
| North | West | East | South |
| East | North | South | West |
| South | East | West | North |
| West | South | North | East |
Notice the pattern: a right turn always moves you one step clockwise around the compass (N→E→S→W→N), and a left turn always moves you one step anticlockwise (N→W→S→E→N). A 180° turn ("turns back", "turns around", "about-turn") always lands you on the exact opposite direction, regardless of whether you think of it as two lefts or two rights.
Shortcut Tip: Memorise the clockwise cycle N→E→S→W→N. Right turn = move one step forward in this cycle. Left turn = move one step backward in this cycle. You never need to re-derive this from scratch in the exam — just recite the cycle.
1.3 Why This Topic Tests Spatial Visualization Under Time Pressure
Direction Sense questions are rarely difficult in terms of the mathematics involved — most reduce to simple addition, subtraction, or the Pythagorean theorem. The real difficulty is cognitive load: holding a changing facing direction and a changing position in your head simultaneously, across multiple steps, while the clock is running. Students who try to "visualize" the whole path in their mind without writing anything down are the ones who make sign errors and mix up left/right. The single biggest score-improving habit in this chapter is to always sketch a quick coordinate grid — even a rough one — the moment you see more than two movements in a question. This book will drill that habit repeatedly.
Solved Example: Setting Up Your First Grid
Question: A man starts at point O, walks 4 km North, then turns right and walks 3 km. How far is he from O?
Step 1 — Fix the origin: Let O = (0, 0), with North = +y direction and East = +x direction.
Step 2 — First leg: Walking 4 km North takes him from (0,0) to (0,4).
Step 3 — Apply the turn rule: He was facing North; a right turn makes him face East (see the turn-rule table above).
Step 4 — Second leg: Walking 3 km East takes him from (0,4) to (3,4).
Step 5 — Find the distance: Since the two legs (4 km North, 3 km East) are perpendicular, use the Pythagorean theorem: distance = √(4² + 3²) = √(16+9) = √25 = 5 km.
Answer: The man is 5 km from O.
2. Basic Movement Problems
The most fundamental Direction Sense question gives you a sequence of statements like "walks X km in direction Y, turns left/right, walks Z km..." and asks for the final position, the distance from the start, or the direction the person is now facing. In this chapter we deal with cases where the net displacement lies along a single straight line — no diagonal (Pythagorean) distance is needed yet; that is covered in Chapter 3. Here, the skill being tested is purely accurate tracking of position and facing direction, leg by leg.
2.1 Theory: Tracking Net Position
Assign coordinates as soon as you start reading the question. Each leg of the journey changes exactly one coordinate (x or y), and each turn changes only the facing direction, not the position. Keep a small running tally of the current facing direction and the current (x, y) position — do not try to hold this in your head beyond two steps.
Solved Example: A Rectangle Path
Question: A man starts facing South and walks 8 km. He turns left and walks 6 km. He turns left again and walks 8 km. He turns left once more and walks 6 km. Where is he now?
O = (0,0). Leg 1: South 8 km → (0,−8). Facing South, a left turn → East (see turn-rule table).
Leg 2: East 6 km → (6,−8). Facing East, a left turn → North.
Leg 3: North 8 km → (6,0). Facing North, a left turn → West.
Leg 4: West 6 km → (0,0).
Answer: He returns exactly to the starting point — four legs and three left turns of a rectangle-shaped path always close back to the start when opposite sides are equal.
Common Traps in Basic Movement Questions
- Forgetting that left/right turns are relative to the CURRENT facing direction, not the original one.
- Confusing "turns and walks" with simply "faces" a new direction without moving.
- Adding distances that are in opposite directions instead of subtracting them (sign errors).
- Assuming a "closed shape" (square/rectangle) always brings you back to start — only true if opposite legs are exactly equal.
Shortcut Tip: If a path returns to the same x-coordinate and the same y-coordinate at the end, the answer is simply "at the starting point" — you do not need to compute any distance. Scan for this before doing detailed arithmetic.
2.2 Practice: Basic Movement Problems
1. Ravi starts from point X, faces North and walks 5 km. He turns right and walks 3 km. He turns right again and walks 5 km. In which direction and how far is he from X?
- (A) 3 km West
- (B) 3 km East
- (C) 8 km East
- (D) 2 km North
Answer: (B) 3 km East
Explanation: Take X as (0,0), North = +y, East = +x. Leg 1: North 5 km → (0,5). Facing North, a right turn faces East. Leg 2: East 3 km → (3,5). Facing East, a right turn faces South. Leg 3: South 5 km → (3,0). This is 3 km to the east of X on the same horizontal line as the start, so the answer is 3 km East.
2. A man starts facing South and walks 8 km. He turns left and walks 6 km. He turns left again and walks 8 km. He turns left once more and walks 6 km. Where is he now with respect to the start?
- (A) 12 km East
- (B) 6 km North
- (C) 8 km South
- (D) Back at the starting point
Answer: (D) Back at the starting point
Explanation: (0,0). South 8 → (0,−8). Facing South, left turn faces East. East 6 → (6,−8). Facing East, left turn faces North. North 8 → (6,0). Facing North, left turn faces West. West 6 → (0,0). He returns exactly to the start — the four legs and three left turns trace a rectangle back to the origin.
3. Starting at a point, a person walks 4 km facing North, turns right, walks 4 km, turns right, walks 4 km, turns right, walks 4 km. What is his final position and which direction does he now face?
- (A) 4 km North of start, facing East
- (B) Back at the start, facing North
- (C) 4 km East of start, facing South
- (D) Back at the start, facing South
Answer: (B) Back at the start, facing North
Explanation: Each right turn cycles N→E→S→W→N. Four equal legs of 4 km with four right turns trace a complete square, so he returns to the exact starting point. Having turned right four times (4×90°=360°), he is again facing North, his original direction.
4. A man is facing East. He turns 90° clockwise, and then another 90° clockwise. Which direction does he face now?
- (A) North
- (B) West
- (C) South
- (D) East
Answer: (B) West
Explanation: Turning clockwise (as seen from above) is the same as turning right. From East, one clockwise turn → South; a second clockwise turn → West. Two 90° clockwise turns total 180°, a reversal, so facing East he now faces exactly opposite: West.
5. A man is facing South. He turns 90° anticlockwise, then 90° anticlockwise again, then 90° anticlockwise once more. Which direction does he face now?
- (A) North
- (B) East
- (C) West
- (D) South
Answer: (C) West
Explanation: Anticlockwise turning is the same as turning left. From South: left turn 1 → East; left turn 2 → North; left turn 3 → West. Three 90° left turns total 270°, so he ends up facing West.
6. A man walks 6 km North and then 6 km South. Where is he with respect to his starting point?
- (A) At the starting point
- (B) 12 km North
- (C) 6 km South
- (D) 6 km North
Answer: (A) At the starting point
Explanation: North 6 → (0,6). South 6 brings him back down by 6 → (0,0). The two equal, opposite legs exactly cancel, so he is back at the starting point — a classic 'there-and-back' case with zero net displacement.
7. A man starts facing East, walks 7 km, turns right, walks 4 km, turns right, walks 7 km, turns right, walks 4 km. Where does he end up?
- (A) 8 km East of start
- (B) Exactly at the starting point
- (C) 4 km North of start
- (D) 14 km South of start
Answer: (B) Exactly at the starting point
Explanation: (0,0). East 7→(7,0). Right turn (E→S), South 4→(7,−4). Right turn (S→W), West 7→(0,−4). Right turn (W→N), North 4→(0,0). Four legs with three right turns close a rectangle exactly back to the start.
8. A person walks 12 km towards North, then turns left and walks 5 km, then turns left again and walks 12 km. How far and in which direction is he from the starting point?
- (A) 5 km East
- (B) 5 km West
- (C) 17 km North
- (D) 12 km West
Answer: (B) 5 km West
Explanation: (0,0). North 12→(0,12). Facing North, left turn → West. West 5→(−5,12). Facing West, left turn → South. South 12→(−5,0). His final point (−5,0) is 5 km to the west of the start, on the same horizontal line — no diagonal distance needed.
9. A man starts at point A facing North and takes a 180° turn. Which direction is he now facing?
- (A) East
- (B) South
- (C) West
- (D) North
Answer: (B) South
Explanation: A 180° turn is a straight about-turn — it does not matter whether you call it 'two rights' or 'two lefts', the result is always the exact opposite direction. Opposite of North is South.
10. A man walks 3 km North, then 3 km East, then 3 km South. Where is he now relative to the starting point?
- (A) 3 km North-East
- (B) 6 km East
- (C) At the starting point
- (D) 3 km East
Answer: (D) 3 km East
Explanation: (0,0). North 3→(0,3). East 3→(3,3). South 3→(3,0). The North and South legs of equal length cancel, leaving only the East leg. Final point (3,0) is 3 km due East of the start.
11. A man is facing West. He turns right twice (two 90° right turns in succession). Which direction does he face now?
- (A) East
- (B) South
- (C) West
- (D) North
Answer: (A) East
Explanation: Facing West, a right turn → North. A second right turn (from North) → East. Two right turns equal a 180° reversal, and the exact opposite of West is East, confirming the answer.
12. A man walks 9 km South, turns left, walks 9 km, turns left again, walks 9 km. In which direction, and how far, must he now walk to return directly to the starting point?
- (A) 9 km East
- (B) 9 km West
- (C) 9 km North
- (D) 18 km West
Answer: (B) 9 km West
Explanation: (0,0). South 9→(0,−9). Facing South, left turn → East. East 9→(9,−9). Facing East, left turn → North. North 9→(9,0). He is now 9 km east of the start point (0,0), on the same horizontal line, so to go directly back he must walk 9 km West.
13. A man walks 2 km East, 2 km North, 2 km West, 2 km North. How far and in which direction is he from the starting point?
- (A) 4 km North
- (B) 2 km North-East
- (C) 4 km East
- (D) 2 km West
Answer: (A) 4 km North
Explanation: (0,0). East 2→(2,0). North 2→(2,2). West 2→(0,2). North 2→(0,4). The East and West legs cancel exactly, leaving a purely vertical displacement: 4 km due North of the start.
3. Shortest Distance / Displacement Problems
When the net movement has both a North-South component and an East-West component, the two are perpendicular to each other, and the straight-line (shortest) distance between the start and end points is found using the Pythagorean theorem: distance = √(North-South component² + East-West component²). This chapter focuses entirely on getting this calculation right, including cases where several legs of the same type must first be combined before the theorem is applied.
3.1 Theory: Constructing the Right Triangle
However many turns a person makes, at the end you only need two numbers: the total net North-South displacement, and the total net East-West displacement. Add up all North legs and subtract all South legs to get one number; add up all East legs and subtract all West legs to get the other. These two numbers are the two legs of a right-angled triangle, and the straight-line distance is its hypotenuse.
Reference: Common Pythagorean Triples Used in This Topic
| Leg 1 (km) | Leg 2 (km) | Hypotenuse / Shortest Distance (km) |
|---|---|---|
| 3 | 4 | 5 |
| 6 | 8 | 10 |
| 5 | 12 | 13 |
| 9 | 12 | 15 |
| 8 | 15 | 17 |
| 7 | 24 | 25 |
| 20 | 21 | 29 |
| 12 | 16 | 20 |
| 10 | 24 | 26 |
| 18 | 24 | 30 |
| 9 | 40 | 41 |
Recognising these triples instantly (without a calculator) is what separates a fast solver from a slow one. Whenever your two perpendicular legs match one of these pairs (or a multiple of one, such as 6-8-10 being 3-4-5 doubled), you can write down the hypotenuse immediately.
Solved Example: Combining Multiple Legs Before Applying Pythagoras
Question: A man starts facing North and walks 5 km. He turns right and walks 15 km. He then turns left and walks 3 km more. Find his shortest distance from the starting point.
O=(0,0). Leg 1: North 5 → (0,5). Facing North, right turn → East.
Leg 2: East 15 → (15,5). Facing East, left turn → North.
Leg 3: North 3 → (15,8).
Before using Pythagoras, combine the two North legs: 5 + 3 = 8 km total North. The East leg stands alone at 15 km.
Distance = √(15² + 8²) = √(225+64) = √289 = 17 km.
Answer: 17 km. Note that jumping straight to √(5²+15²+3²) — treating all three legs as independent — would be wrong; only perpendicular, unlike-axis legs go into the Pythagorean sum, and same-axis legs must be combined (added or subtracted) first.
Common Traps in Shortest-Distance Questions
- Applying the Pythagorean theorem to legs that are NOT perpendicular (e.g. two legs both along North-South).
- Forgetting to net off opposite-direction legs (e.g. 9 km East then 9 km West cancel to zero) before computing the hypotenuse.
- Mixing up which two numbers are the "legs" of the triangle versus the answer (the hypotenuse) when picking from the options.
- Arithmetic slips while squaring two-digit numbers — always double check with a rough triple pattern.
Shortcut Tip: Before reaching for a calculator-style square-root, check whether your two combined legs match a known triple (3-4-5, 5-12-13, 8-15-17, 7-24-25, 20-21-29, or a multiple of these). Most exam questions are deliberately built around exact triples so that the answer is a whole number.
3.2 Practice: Shortest Distance / Displacement Problems
14. A man walks 4 km East and then 3 km North. What is his shortest (straight-line) distance from the starting point?
- (A) 7 km
- (B) 6 km
- (C) 4 km
- (D) 5 km
Answer: (D) 5 km
Explanation: East and North legs are perpendicular, so they form the two legs of a right triangle: 4 km and 3 km. Distance = √(4²+3²) = √(16+9) = √25 = 5 km (the classic 3-4-5 triple).
15. A man walks 8 km North and then 6 km East. Find his shortest distance from the start.
- (A) 14 km
- (B) 12 km
- (C) 8 km
- (D) 10 km
Answer: (D) 10 km
Explanation: Perpendicular legs of 8 km and 6 km. Distance = √(8²+6²) = √(64+36) = √100 = 10 km (a 6-8-10 triple, i.e. 3-4-5 scaled by 2).
16. A man walks 5 km South, then 12 km East. Find his shortest distance from the starting point.
- (A) 17 km
- (B) 13 km
- (C) 7 km
- (D) 15 km
Answer: (B) 13 km
Explanation: Perpendicular legs of 5 km and 12 km. Distance = √(5²+12²) = √(25+144) = √169 = 13 km — the well-known 5-12-13 triple.
17. A man walks 9 km West, then 12 km North. Find his shortest distance from the starting point.
- (A) 15 km
- (B) 21 km
- (C) 3 km
- (D) 20 km
Answer: (A) 15 km
Explanation: Legs of 9 km and 12 km are perpendicular (West-North). Distance = √(9²+12²) = √(81+144) = √225 = 15 km (9-12-15, a 3-4-5 triple scaled by 3).

- (A) 23 km
- (B) 17 km
- (C) 7 km
- (D) 19 km
Answer: (B) 17 km
Explanation: Perpendicular legs 15 km and 8 km. Distance = √(15²+8²) = √(225+64) = √289 = 17 km (the 8-15-17 triple).
19. A man starts facing North and walks 5 km. He turns right and walks 15 km. He then turns left and walks 3 km more. Find his shortest distance from the starting point.
- (A) 23 km
- (B) 20 km
- (C) 13 km
- (D) 17 km
Answer: (D) 17 km
Explanation: (0,0). North 5→(0,5). Facing North, right turn → East; East 15→(15,5). Facing East, left turn → North; North 3→(15,8). Combine the two North legs first: 5+3 = 8 km net North; East leg = 15 km. Distance = √(15²+8²) = √(225+64) = √289 = 17 km — note how two separate legs in the same direction had to be added before applying Pythagoras.
20. A man walks 3 km South, turns right, walks 24 km, turns left, walks 4 km. Find his shortest distance from the starting point.
- (A) 31 km
- (B) 28 km
- (C) 21 km
- (D) 25 km
Answer: (D) 25 km
Explanation: (0,0). South 3→(0,−3). Facing South, right turn → West; West 24→(−24,−3). Facing West, left turn → South; South 4→(−24,−7). Combine the two South legs: 3+4 = 7 km net South; West leg = 24 km. Distance = √(24²+7²) = √(576+49) = √625 = 25 km.
21. A man walks 9 km West and then 40 km South. Find his shortest distance from the starting point.
- (A) 49 km
- (B) 31 km
- (C) 41 km
- (D) 45 km
Answer: (C) 41 km
Explanation: Perpendicular legs 9 km and 40 km. Distance = √(9²+40²) = √(81+1600) = √1681 = 41 km — a less common but exact triple (9-40-41), worth memorising alongside 3-4-5 and 5-12-13.

- (A) 41 km
- (B) 29 km
- (C) 19 km
- (D) 35 km
Answer: (B) 29 km
Explanation: Perpendicular legs 20 km and 21 km. Distance = √(20²+21²) = √(400+441) = √841 = 29 km (the 20-21-29 triple).
23. A man walks 12 km North and then 16 km East. Find his shortest distance from the starting point.
- (A) 28 km
- (B) 20 km
- (C) 14 km
- (D) 24 km
Answer: (B) 20 km
Explanation: Perpendicular legs 12 km and 16 km. Distance = √(12²+16²) = √(144+256) = √400 = 20 km (12-16-20, i.e. 3-4-5 scaled by 4).

25. A man walks 18 km East and then 24 km North. Find his shortest distance from the starting point.
- (A) 42 km
- (B) 6 km
- (C) 36 km
- (D) 30 km
Answer: (D) 30 km
Explanation: Perpendicular legs 18 km and 24 km. Distance = √(18²+24²) = √(324+576) = √900 = 30 km (3-4-5 scaled by 6).
26. A man starts facing North and walks 20 km. He turns right and walks 9 km. He turns left and walks 12 km. He turns left again and walks 9 km. Find his shortest distance from the starting point.
- (A) 41 km
- (B) 32 km
- (C) 23 km
- (D) 14 km
Answer: (B) 32 km
Explanation: (0,0). North 20→(0,20). Right turn (N→E), East 9→(9,20). Left turn (E→N), North 12→(9,32) [running North total 20+12=32]. Left turn (N→W), West 9→(0,32). The East (9) and West (9) legs exactly cancel, leaving a pure vertical displacement of 32 km North — a good reminder to watch signs, not just add every number blindly.
4. Final Direction Questions
A second, distinct question type asks not "how far" but "in which direction" — either the direction of the final point from the start (which may be a diagonal direction such as North-East), or the direction the person is now facing after a series of turns. This chapter also introduces movements given directly along a diagonal (45°) direction such as North-East or South-West, which must be resolved into their North/South and East/West components before they can be combined with other legs.
4.1 Theory: Diagonal (45°) Movements
When a person walks a distance d in a diagonal direction such as North-East, that single movement has an equal component along North and along East (each of size d/√2). In most SSC/RRB questions, diagonal legs are combined with other diagonal legs specifically so that the √2 terms cancel out neatly, leaving a clean answer along one of the four main directions — this is a favourite exam trick worth recognising on sight.
Solved Example: Two Diagonal Legs That Cancel Cleanly
Question: A man walks 10 km towards North-East and then 10 km towards North-West. In which direction is he now from the starting point?
Resolve NE (10 km) into components: East = 10/√2, North = 10/√2.
Resolve NW (10 km) into components: West = 10/√2, North = 10/√2.
Add the East/West components: (10/√2) East and (10/√2) West are equal and opposite, so they cancel exactly to zero.
Add the North components: 10/√2 + 10/√2 = a positive net North value.
Answer: Since only the North component survives, the man is due North of the starting point.
4.2 Theory: Direction vs. Facing — Two Different Questions
Be alert to exactly what is being asked. "In which direction is he from the starting point?" is about the POSITION of the final point relative to the start (a straight line drawn from start to end). "Which direction is he facing?" is about the ORIENTATION of the person at the end of the journey, which depends only on the sequence of turns made, not on how far he walked at each stage or where he ended up. These two answers can be completely different for the same journey, and exams frequently test both in the same question set.
Common Traps in Final Direction Questions
- Giving the direction from the END point back to the START (the reverse direction) instead of the direction asked for, or vice versa — always identify exactly which of the two points is the reference point.
- Confusing "facing direction" (depends only on turns) with "direction of displacement" (depends on distances too).
- Forgetting that diagonal directions (NE, SE, SW, NW) are valid, exact answers when North-South and East-West components come out equal — do not force an answer into only N/E/S/W.
- Sign errors while resolving a diagonal leg into components (forgetting that South and West components are negative).
Shortcut Tip: If a question mentions two diagonal legs of EQUAL length, check first whether the "shared" component (the one appearing in both) is in the same direction (they add) or opposite directions (they cancel). This one check saves you from resolving components in full for most such questions.
4.3 Practice: Final Direction Questions
27. A man walks 5 km North and then 5 km East. In which direction is he from the starting point?
- (A) North
- (B) East
- (C) South-East
- (D) North-East
Answer: (D) North-East
Explanation: Since the North leg (5 km) equals the East leg (5 km), the resultant displacement lies exactly on the 45° diagonal between North and East — that is, North-East.
28. A man walks 8 km East and then 8 km South. In which direction is he from the starting point?
- (A) South-East
- (B) East
- (C) South
- (D) South-West
Answer: (A) South-East
Explanation: Equal East and South legs (8 km each) place the final point exactly on the diagonal between East and South, i.e. South-East.
29. A man walks 6 km North and then 6 km West. In which direction is he from the starting point?
- (A) North
- (B) West
- (C) South-West
- (D) North-West
Answer: (D) North-West
Explanation: Equal North and West legs (6 km each) give a resultant exactly along the North-West diagonal.
30. A man walks 4 km South and then 4 km West. In which direction is he from the starting point?
- (A) South-West
- (B) South
- (C) West
- (D) North-West
Answer: (A) South-West
Explanation: Equal South and West legs (4 km each) place the final point on the South-West diagonal from the start.
31. A man walks 5 km towards North-East and then 5 km towards South-East. In which direction is he now from the starting point?
- (A) North
- (B) South
- (C) North-East
- (D) East
Answer: (D) East
Explanation: Resolve each diagonal leg into components: NE (5 km) = (5/√2 East, 5/√2 North); SE (5 km) = (5/√2 East, 5/√2 South). Adding: East components add (5/√2+5/√2), North and South components are equal and opposite so they cancel exactly. Net displacement is due East.
32. A man walks 10 km towards North-East and then 10 km towards North-West. In which direction is he from the starting point?
- (A) North
- (B) East
- (C) West
- (D) South
Answer: (A) North
Explanation: NE (10 km) = (10/√2 East, 10/√2 North); NW (10 km) = (10/√2 West, 10/√2 North). The East and West components are equal and opposite and cancel; the two North components add up. Net displacement is due North.
33. A man walks 10 km towards South-West and then 10 km towards South-East. In which direction is he from the starting point?
- (A) East
- (B) West
- (C) North
- (D) South
Answer: (D) South
Explanation: SW (10 km) = (10/√2 West, 10/√2 South); SE (10 km) = (10/√2 East, 10/√2 South). East and West components cancel; both South components add. Net displacement is due South.
34. A man walks 10 km towards North-East and then 10 km towards South-West. Where is he now with respect to the starting point?
- (A) 20 km North
- (B) Back at the starting point
- (C) 20 km East
- (D) 10 km South
Answer: (B) Back at the starting point
Explanation: South-West is the exact opposite direction of North-East. Walking 10 km NE and then 10 km SW simply retraces the same line back — he returns exactly to the starting point.
35. A man faces North and turns 45° clockwise. Which direction is he facing now?
- (A) North-West
- (B) East
- (C) North-East
- (D) South-East
Answer: (C) North-East
Explanation: Clockwise = towards the right. A 45° clockwise turn from North lands exactly halfway between North and East, i.e. North-East.
36. A man faces East and turns 135° anticlockwise. Which direction is he facing now?
- (A) South-West
- (B) North
- (C) South
- (D) North-West
Answer: (D) North-West
Explanation: Measuring clockwise from North: East = 90°. Anticlockwise turning decreases this angle: 90° − 135° = −45°, which is the same as 360°−45° = 315°. On the compass, 315° corresponds to North-West.
37. A man faces South-West and turns 90° clockwise. Which direction is he facing now?
- (A) North-East
- (B) North-West
- (C) South-East
- (D) North
Answer: (B) North-West
Explanation: South-West is at 225° (measuring clockwise from North). A 90° clockwise turn adds 90°: 225°+90° = 315°, which is North-West.
38. A man walks 12 km East and then 12 km North to reach point B from point O. In which direction is point O from point B?
- (A) North-East
- (B) South-East
- (C) North-West
- (D) South-West
Answer: (D) South-West
Explanation: Since the East and North legs are equal, B is exactly North-East of O. The reverse direction — from B back to O — is therefore exactly opposite: South-West. This tests the common trap of giving the direction of the starting point instead of the direction asked for (or vice versa).
5. Shadow-Based Direction Problems
A recurring cross-topic variant of Direction Sense uses the position of a shadow cast by the sun to determine which way a person is facing, or vice versa. These questions rely on just two solid facts about the sun's apparent movement, applied very literally.
5.1 Theory: Sun Position and Shadow Direction
- In the morning (sunrise), the sun is in the East. A shadow always falls directly opposite the sun, so every shadow in the morning points towards the West — regardless of which way the person casting it is facing.
- In the evening (sunset), the sun is in the West. Every shadow in the evening points towards the East.
- At noon, in most of India, the sun is close to overhead and slightly towards the South, so shadows are very short and point slightly towards the North.
Reference: Sun and Shadow Table
| Time of day | Sun's direction | Shadow falls towards |
|---|---|---|
| Morning / Sunrise | East | West |
| Noon (approx., India) | South (roughly overhead) | North (very short) |
| Evening / Sunset | West | East |
The direction the SHADOW itself points is an absolute compass direction fixed only by the time of day — it never depends on which way the person is facing. What DOES depend on the person's facing direction is whether that shadow appears "in front", "behind", "to the left" or "to the right" of them — and this is exactly where the classic exam trap lives.
Solved Example: The "Shadow to the Left" Trick
Question: In the morning, Rahul's shadow falls exactly to his right. Which direction is Rahul facing?
Step 1: It is morning, so the shadow's absolute direction is West (opposite the East-rising sun) — this is fixed and does not depend on Rahul at all.
Step 2: We are told this Westward shadow is on Rahul's RIGHT hand side. So his right hand currently points West.
Step 3: Check the turn-rule table for which facing direction has "right = West": Facing South gives right = West.
Answer: Rahul is facing South.
Common Traps in Shadow-Based Questions
- Assuming the shadow's direction changes depending on which way the person faces — it does not; only "front/back/left/right" (relative) changes, not the absolute compass direction of the shadow.
- Mixing up morning (shadow West) and evening (shadow East) — always re-check which time of day the question states before applying the rule.
- Treating "shadow falls in front" and "sun is behind" as needing different logic — they are two ways of describing the exact same geometry (shadow is always opposite the sun).
- Forgetting that at noon in India, shadows are very short and point roughly North, which can seem counter-intuitive at first.
Shortcut Tip: First fix the ABSOLUTE shadow direction using only the time of day (West in morning, East in evening) — do this before you even look at "left/right/front/back". Then use the turn-rule table exactly as you would for any other left/right question.
5.2 Practice: Shadow-Based Direction Problems
39. In the morning, Rahul's shadow falls exactly to his right. Which direction is Rahul facing?
- (A) North
- (B) South
- (C) East
- (D) West
Answer: (B) South
Explanation: In the morning the sun rises in the East, so every shadow (regardless of who is facing which way) falls on the ground towards the West — directly opposite the sun. If that Westward shadow is on Rahul's right hand side, then his right hand points West. Right = West only when facing South, so Rahul faces South.
40. In the evening, Meena's shadow falls exactly to her right. Which direction is Meena facing?
- (A) South
- (B) East
- (C) West
- (D) North
Answer: (D) North
Explanation: In the evening the sun sets in the West, so every shadow falls towards the East. If this Eastward shadow is on Meena's right, her right hand points East. Right = East only when facing North, so Meena faces North.
41. At sunrise, a man's shadow falls exactly to his left. Which direction is he facing?
- (A) South
- (B) East
- (C) North
- (D) West
Answer: (C) North
Explanation: At sunrise the sun is in the East, so the shadow always falls towards the West. If the shadow is on his left, his left hand points West. Left = West only when facing North, so he faces North.
42. Suresh is facing East in the morning. In which direction does his shadow fall?
- (A) East
- (B) North
- (C) South
- (D) West
Answer: (D) West
Explanation: The absolute compass direction of a shadow depends only on where the sun is, not on which way the person is facing. In the morning the sun is in the East, so every shadow — no matter the person's facing direction — falls towards the West.
43. In which direction does a pole's shadow fall in the evening?
- (A) West
- (B) North
- (C) East
- (D) South
Answer: (C) East
Explanation: In the evening the sun is in the West, and a shadow always falls directly opposite the sun. So the shadow falls towards the East.
44. In the morning, a man notices that his own shadow falls exactly in front of him as he walks. In which direction is he walking?
- (A) East
- (B) North
- (C) South
- (D) West
Answer: (D) West
Explanation: Morning shadows fall towards the West (sun in the East). If the shadow is in front of him, he must be walking towards the same direction the shadow lies in — that is, towards the West.
45. In the evening, a man's shadow falls exactly behind him. In which direction is he facing?
- (A) East
- (B) West
- (C) North
- (D) South
Answer: (B) West
Explanation: Evening shadows fall towards the East (sun in the West). 'Behind' means opposite to his facing direction. If the shadow (East) is behind him, he must be facing the opposite of East, which is West.
46. Early in the morning, Anil starts walking with the sun exactly behind him. In which direction is he walking?
- (A) East
- (B) North
- (C) West
- (D) South
Answer: (C) West
Explanation: In the morning the sun is in the East. If the sun is behind Anil, he is facing away from the East, i.e. facing West.
47. In the evening, Bina walks such that the sun is exactly to her left. In which direction is she walking?
- (A) South
- (B) East
- (C) North
- (D) West
Answer: (C) North
Explanation: In the evening the sun is in the West. If the sun is on Bina's left, her left hand points West. Left = West only when facing North, so Bina is walking North.
48. At a certain time of day, the shadow of a pole falls exactly to the North of the pole. In which direction is the sun located at that time?
- (A) South
- (B) North
- (C) East
- (D) West
Answer: (A) South
Explanation: A shadow always falls directly opposite the sun's position. If the shadow points North, the sun must be in the exact opposite direction: South. (This matches the everyday observation that around noon in most of India the sun is somewhat towards the South, so shadows point slightly North.)
49. It is evening. Kavita is facing a pole and notices its shadow falling to her left. Which direction is Kavita facing?
- (A) North
- (B) East
- (C) West
- (D) South
Answer: (D) South
Explanation: Evening shadows fall towards the East. If the shadow is on Kavita's left, her left hand points East. Left = East only when facing South, so Kavita faces South.
50. In the evening, the shadow of a pole falls to Deepak's right. Which direction is Deepak facing?
- (A) North
- (B) South
- (C) East
- (D) West
Answer: (A) North
Explanation: Evening shadows fall towards the East. If the shadow is on Deepak's right, his right hand points East. Right = East only when facing North, so Deepak faces North.
51. A man is facing North in the morning. He turns 90° to his right and starts walking in the new direction. Relative to this new walking direction, where does his shadow now fall — front, back, left or right?
- (A) Behind him (back)
- (B) In front of him
- (C) To his left
- (D) To his right
Answer: (A) Behind him (back)
Explanation: Morning shadows are always towards the West. Facing North, a right turn makes him face East. For a person facing East: front = East, back = West, left = North, right = South. Since the shadow is towards the West, it now falls exactly behind him.
6. Clock-Based Direction and Angle Problems
SSC/RRB Reasoning papers sometimes combine the "clock" topic with Direction Sense by treating the clock face itself as a compass — the 12 mark is taken as North, and each of the twelve hour-marks around the dial is 30° clockwise from the previous one (since 360° ÷ 12 = 30°). This is a brief bridge topic: a small number of questions in most papers, but worth knowing cold since it costs no extra formula beyond what you already know.
6.1 Theory: The Clock Face as a Compass
- 12 o'clock position = North (0°), 3 o'clock = East (90°), 6 o'clock = South (180°), 9 o'clock = West (270°) — exactly matching the compass rose.
- Each hour mark is worth 30° clockwise; e.g. the 1 mark is 30° clockwise from North, the 2 mark is 60°, and so on.
- If the clock is described as "rotated" so that some other number now points North (or another direction), simply shift every other mark by the same rotation before re-reading directions.
Solved Example: Hour Hand as a Compass Needle
Question: On a wall clock, if the 12 mark points North, in which direction does the hour hand point at 3 o'clock?
Step 1: Each hour mark = 30° clockwise from the previous one.
Step 2: The 3 mark is 3 × 30° = 90° clockwise from the 12 mark (North).
Step 3: 90° clockwise from North is exactly East on the compass.
Answer: The hour hand points East.
Common Traps in Clock-Direction Questions
- Forgetting that this trick only lines up exactly at the 12, 3, 6 and 9 marks (multiples of 90°) — other hour marks (like 1, 2, 4, 5...) do not correspond to a named compass direction such as NE or SE.
- Confusing the hour hand with the minute hand when the question specifies one or the other.
- Forgetting to re-map ALL directions if the clock face itself has been described as rotated.
Shortcut Tip: Only trust this method at the four clean quarter positions (12, 3, 6, 9), which map to N, E, S, W respectively. If a question asks about 1, 2, 4, 5, 7, 8, 10 or 11 o'clock, treat it purely as a degree calculation (multiples of 30°) rather than trying to force it onto a named direction.
6.2 Practice: Clock-Based Direction Problems
52. On a wall clock, if the 12 mark points North, in which direction does the hour hand point when it shows 3 o'clock?
- (A) West
- (B) South
- (C) East
- (D) North
Answer: (C) East
Explanation: Treating the clock face as a compass with 12 = North, each hour mark is 30° clockwise from the previous one (360°/12). The 3 mark is 3×30° = 90° clockwise from North, which is exactly East.
53. If 12 o'clock position points North, in which direction does the hour hand point at 6 o'clock?
- (A) North
- (B) South
- (C) East
- (D) West
Answer: (B) South
Explanation: The 6 mark is 6×30° = 180° from the 12 mark, i.e. directly opposite North, which is South.
54. If 12 o'clock position points North, in which direction does the hour hand point at 9 o'clock?
- (A) East
- (B) West
- (C) North
- (D) South
Answer: (B) West
Explanation: The 9 mark is 9×30° = 270° clockwise from North, which corresponds to West.
55. With 12 o'clock as North, at 3 o'clock the hour hand points East. Through how many degrees, measured clockwise from North, has it moved?
- (A) 60°
- (B) 120°
- (C) 180°
- (D) 90°
Answer: (D) 90°
Explanation: From 12 to 3 is a quarter of the full circle: (3/12)×360° = 90°, taking it from North to East.
56. With 12 o'clock as North, at 9 o'clock the hour hand points West. Through how many degrees, measured anticlockwise from North, has it moved?
- (A) 270°
- (B) 45°
- (C) 90°
- (D) 180°
Answer: (C) 90°
Explanation: Measured clockwise, 9 o'clock is 270° from North; measured the shorter way, anticlockwise, it is only 360°−270° = 90° from North to West.
57. If the minute hand points to 12 (North) and the hour hand points to 3 (East), what time does the clock show?
- (A) 9:00
- (B) 3:00
- (C) 12:15
- (D) 6:00
Answer: (B) 3:00
Explanation: Hour hand exactly on 3 with the minute hand exactly on 12 can only happen at 3:00 sharp.
58. With 12 as North, the hour hand of a clock points South. A man stands facing the same direction as the hour hand. Which direction is he facing?
- (A) North
- (B) South
- (C) East
- (D) West
Answer: (B) South
Explanation: Hour hand pointing South (this happens at 6 o'clock, since 6 is 180° from 12/North) means the man, facing the same way, is also facing South.
59. On a clock with 12 = North, both hands overlap at 12 (pointing North). Later, the hour hand has moved to point East. What is the minimum time, in hours, that has passed on a 12-hour clock?
- (A) 3 hours
- (B) 6 hours
- (C) 1 hour
- (D) 9 hours
Answer: (A) 3 hours
Explanation: The hour hand moves from the 12 mark to the 3 mark, i.e. one quarter of the clock face, which takes 3 hours (out of the 12-hour cycle).
60. At 3:00, with 12 = North, the hour hand points East (90°) and the minute hand points North (0°). Which direction bisects the angle between the two hands?
- (A) South-East
- (B) North-East
- (C) North-West
- (D) South
Answer: (B) North-East
Explanation: The hour hand is at 90° (East) and the minute hand is at 0° (North). The angle between them is 90°, and its bisector lies at 45° from North, which is exactly North-East.
61. At 6:00, with 12 = North, the hour hand points South (180°) and the minute hand points North (0°/360°). Walking exactly midway between the two hands by turning clockwise from North, which direction would this be?
- (A) West
- (B) South
- (C) North
- (D) East
Answer: (D) East
Explanation: The two hands are 180° apart. Turning clockwise from North (0°) by half of 180°, i.e. 90°, lands on East. (The same angle also has a second, anticlockwise, bisector at West — but taken in the clockwise sense from North, the answer is East.)
62. With 12 as North, if the clock is turned so that the 12 mark now points East, in which direction does the 6 mark point?
- (A) East
- (B) North
- (C) South
- (D) West
Answer: (D) West
Explanation: The 6 mark is always exactly opposite the 12 mark (180° apart) on the clock face. If 12 now points East, 6 must point exactly opposite: West.
63. With 12 as North, if the clock face is rotated so that 12 now points South, in which direction does the 3 mark point?
- (A) East
- (B) West
- (C) North
- (D) South
Answer: (B) West
Explanation: Normally 3 is 90° clockwise from 12. If 12 has been rotated to point South, then 3 (still 90° clockwise from wherever 12 points) is 90° clockwise from South, which is West.
64. With 12 o'clock as North, the hour hand points West at 9 o'clock. A boy starts walking in the exact opposite direction to the hour hand. Which direction is he walking?
- (A) West
- (B) North
- (C) East
- (D) South
Answer: (C) East
Explanation: The hour hand points West. The exact opposite direction to West is East, so the boy walks East.
7. Direction Sense with Blood Relations and Seating Arrangement
Exams frequently mix Direction Sense with two other favourite Reasoning topics: Blood Relations and Seating Arrangement. In these hybrid questions, a short relationship puzzle ("his mother is the only daughter of my mother") is used only to identify WHO a person is, after which the actual question is a completely standard direction-and-position problem. Do not let the relationship clue intimidate you — solve it separately, then switch entirely into coordinate-grid mode for the direction part.
7.1 Theory: Two Independent Steps
Always separate these hybrid questions into two clearly distinct steps. Step 1: work out the blood relation using standard family-tree logic, ignoring directions entirely. Step 2: once you know who is who, redraw the direction/position facts as a coordinate grid exactly as in earlier chapters, ignoring the relationship names — treat each person simply as a labelled point.
Solved Example: Relation and Direction, Solved Separately
Question: Pointing to a photograph, Aarav said, "The girl in the photo is my father's only son's daughter." If Aarav's house is South of the girl's house, how is the girl related to Aarav, and in which direction is the girl's house from Aarav's house?
Step 1 (relation): "My father's only son" — if Aarav's father has only one son, that son must be Aarav himself. So "my father's only son's daughter" = Aarav's own daughter.
Step 2 (direction): We are told Aarav's house is South of the girl's house. Reversing this: the girl's house is North of Aarav's house.
Answer: The girl is Aarav's daughter, and her house is to the North of Aarav's house.
7.2 Theory: Seating Rows and Facing Direction
When people are seated in a row and all face the same direction, "immediate left" and "immediate right" translate directly into compass directions using the same turn-rule logic from Chapter 1 — just applied to a stationary row instead of a walking path.
- Row facing North: left-hand side of the row = West, right-hand side = East.
- Row facing South: left-hand side of the row = East, right-hand side = West (exactly reversed from facing North).
- Row facing East: left-hand side = North, right-hand side = South.
- Row facing West: left-hand side = South, right-hand side = North.
Common Traps in Relation/Seating + Direction Questions
- Trying to solve the relationship and the direction in one single mental step — always separate them.
- Applying the "facing North" left/right rule to a row that is actually stated to be facing South (or vice versa).
- Forgetting that in a circular arrangement, "facing the centre" and "facing outward" give opposite answers for the same seat position.
Shortcut Tip: For seating-row direction questions, mentally stand IN the row facing the stated direction, and use the exact same turn-rule table from Chapter 1 (a stationary "left/right" is identical logic to a walking "turns left/right").
7.3 Practice: Direction Sense with Blood Relations and Seating
65. A is B's brother. B stays 5 km to the North of A. C, who is B's sister, stays 5 km to the East of B. In which direction is C from A?
- (A) North-West
- (B) South-East
- (C) North-East
- (D) East
Answer: (C) North-East
Explanation: Take A as (0,0). B is North of A: (0,5). C is East of B: (5,5). Since C's position is equally North and East of A, C is exactly North-East of A.
66. Point P is directly South of point Q. Point R, who is Q's son, is directly East of P. In which direction is R from Q?
- (A) North-East
- (B) South-East
- (C) South-West
- (D) North
Answer: (B) South-East
Explanation: Let Q be (0,0). P is South of Q: (0,−d). R is East of P: (e,−d). R lies south of Q and east of Q both, so R is to the South-East of Q.
67. Pointing to a man, Sita said, 'His mother is the only daughter of my mother.' If the man's house is North of Sita's house, and Sita's house is West of their office, in which direction is the man's house from the office, and how is he related to Sita?
- (A) North-East; he is Sita's brother
- (B) North-West; he is Sita's son
- (C) South-West; he is Sita's nephew
- (D) North-West; he is Sita's nephew
Answer: (B) North-West; he is Sita's son
Explanation: 'The only daughter of my mother' is Sita herself. So the man's mother is Sita, making the man Sita's son. Direction: office is East of Sita's house, so Sita's house is West of the office, i.e. at (−d,0) taking office as origin. The man's house is North of Sita's house: (−d,h). This lies North-West of the office.
68. A and B are sisters; A's house is 3 km East of B's house. C, A's brother, stays 3 km North of A's house. In which direction is C's house from B's house?
- (A) North-West
- (B) South-East
- (C) East
- (D) North-East
Answer: (D) North-East
Explanation: Let B be (0,0). A is East of B: (3,0). C is North of A: (3,3). Since C is equally East and North of B, C's house is North-East of B's house.
69. Six friends sit in a row, all facing North. Aman sits to the immediate left of Bala. In which direction is Aman with respect to Bala?
- (A) East
- (B) West
- (C) North
- (D) South
Answer: (B) West
Explanation: When a row of people faces North, each person's left hand points West and right hand points East. Aman, sitting at Bala's left-hand side, is therefore positioned to the West of Bala.
70. In a row of students all facing South, Chetan sits to the immediate right of Deepa. In which direction is Chetan with respect to Deepa?
- (A) East
- (B) West
- (C) North
- (D) South
Answer: (B) West
Explanation: Facing South, a person's right hand points West (and left hand points East) — exactly the reverse of facing North. Chetan, at Deepa's right-hand side, is therefore West of Deepa.
71. In a row of people all facing East, X sits to the immediate left of Y. In which direction is X with respect to Y?
- (A) South
- (B) East
- (C) North
- (D) West
Answer: (C) North
Explanation: Facing East, a person's left hand points North (and right hand points South). X, at Y's left-hand side, is therefore North of Y.
72. In a row of people all facing West, P sits to the immediate right of Q. In which direction is P with respect to Q?
- (A) South
- (B) East
- (C) North
- (D) West
Answer: (C) North
Explanation: Facing West, a person's right hand points North (and left hand points South). P, at Q's right-hand side, is therefore North of Q.
73. Pointing to a photograph, Aarav said, 'The girl in the photo is my father's only son's daughter.' If Aarav's house is South of the girl's house, how is the girl related to Aarav, and in which direction is the girl's house from Aarav's house?
- (A) Sister; South
- (B) Niece; North
- (C) Daughter; North
- (D) Daughter; East
Answer: (C) Daughter; North
Explanation: 'My father's only son' is Aarav himself (since he is the only son of his father). So the girl is Aarav's own daughter. Since Aarav's house is South of the girl's house, the girl's house is, in reverse, North of Aarav's house.
74. Eight people sit in a circle, all facing the centre. A sits to the exact South of the centre. Which direction is A facing?
- (A) North
- (B) South
- (C) East
- (D) West
Answer: (A) North
Explanation: A person facing the centre from the South side of the circle must be looking towards the centre, i.e. towards the North. So A faces North.
75. In a circular arrangement, all members face outward, away from the centre. B sits to the exact North of the centre. Which direction is B facing?
- (A) South
- (B) North
- (C) East
- (D) West
Answer: (B) North
Explanation: Facing outward means facing further away from the centre. Since B is on the North side of the circle, facing outward means facing further North. So B faces North.
76. Kunal walks 4 km North from his house to reach his school. His friend's house is 3 km East of the school. Kunal is the elder brother of his friend's mother. In which general direction is the friend's house from Kunal's house?
- (A) North-West
- (B) South-East
- (C) East
- (D) North-East
Answer: (D) North-East
Explanation: Let Kunal's house be (0,0). School is North of it: (0,4). Friend's house is East of the school: (3,4). Since the friend's house lies both North and East of Kunal's house, it is in the North-East direction from Kunal's house (the family relationship here is only context and does not affect the direction calculation).
8. Multi-Turn Complex Path Problems
The most demanding Direction Sense questions describe five, six or even seven separate movements with repeated turns. These cannot be solved reliably by visualization alone — the coordinate-grid method is not optional here, it is essential. This chapter works through several long examples in full, leg by leg, to build the discipline needed to avoid errors under exam time pressure.
8.1 Theory: The Coordinate-Grid Method for Long Paths
For any path with several legs, write a small table with one row per leg: the direction walked, the distance, and the running (x, y) position after that leg. Update the current facing direction on a separate line each time a turn is mentioned. Never skip a leg — with five or more movements, skipping even one addition is enough to change the final answer completely.
Solved Example: A Six-Leg Spiral Path
Question: A man starts from a point facing North and walks 25 km. He turns right and walks 30 km. He turns right and walks 10 km. He turns right and walks 15 km. He turns right and walks 6 km. He turns right and walks 5 km. Find the distance between the starting point and his final position.
O=(0,0), facing North.
Leg 1 — North 25 km → (0,25). Turn right: North→East.
Leg 2 — East 30 km → (30,25). Turn right: East→South.
Leg 3 — South 10 km → (30,15). Turn right: South→West.
Leg 4 — West 15 km → (15,15). Turn right: West→North.
Leg 5 — North 6 km → (15,21). Turn right: North→East.
Leg 6 — East 5 km → (20,21).
Net North-South component: 25 (N) − 10 (S) + 6 (N) = 21 km North.
Net East-West component: 30 (E) − 15 (W) + 5 (E) = 20 km East.
Distance = √(20² + 21²) = √(400+441) = √841 = 29 km.
Answer: 29 km from the starting point.
8.2 Theory: Facing-Only Questions Need No Distances at All
A useful shortcut for long, multi-turn questions: if the question ONLY asks which direction the person is finally facing (not their position or distance), you can completely ignore every distance given in the problem. Only the sequence of turns matters. Simply apply each turn, one after another, to the compass cycle N→E→S→W→N (for right turns) or N→W→S→E→N (for left turns), starting from the stated initial facing direction.
Common Traps in Multi-Turn Complex Problems
- Losing track of the current facing direction partway through a long sequence — always update it explicitly after every single turn, never trust memory alone.
- Sign errors when combining several legs along the same axis — a North leg is +y, a South leg is −y; keep signs consistent throughout.
- Confusing a clockwise (right) turn with an anticlockwise (left) turn partway through a long list — re-check the turn-rule table for every single turn rather than assuming a pattern continues.
- "Turns to face" a new direction (no movement) being confused with "turns and walks" (movement follows) — read each sentence carefully for whether distance is attached to that step.
- Stopping the calculation one leg too early, especially when an earlier leg brings the person back near the starting point, creating a false sense that the journey is already "closed".
Shortcut Tip: For any question with 4 or more legs, physically write out a mini-table (Leg | Direction | Distance | New Position) on your rough sheet before attempting to pick an answer. The 15–20 seconds this costs is far cheaper than a wrong answer or a restart.
8.3 Practice: Multi-Turn Complex Path Problems
77. A man starts from point X, facing North, and walks 10 km. He turns right and walks 5 km. He turns right again and walks 10 km. He turns left and walks 4 km. He turns left again and walks 12 km. Find the shortest distance between X and his final position.
- (A) 15 km
- (B) 21 km
- (C) 9 km
- (D) 13 km
Answer: (A) 15 km
Explanation: X=(0,0). North 10→(0,10). Right turn (N→E), East 5→(5,10). Right turn (E→S), South 10→(5,0). Left turn (S→E), East 4→(9,0). Left turn (E→N), North 12→(9,12). Distance = √(9²+12²) = √(81+144) = √225 = 15 km.

- (D) 17 km
Answer: (D) 17 km
Explanation: (0,0). East 20→(20,0). Left turn (E→N), North 10→(20,10). Left turn (N→W), West 20→(0,10). Right turn (W→N), North 5→(0,15). Right turn (N→E), East 8→(8,15). Distance = √(8²+15²) = √(64+225) = √289 = 17 km.
79. A man starts facing South and walks 15 km. He turns left and walks 10 km. He turns left again and walks 20 km. He turns right and walks 14 km. He turns right again and walks 12 km. Find his distance from the starting point.
- (A) 31 km
- (B) 19 km
- (C) 37 km
- (D) 25 km
Answer: (D) 25 km
Explanation: (0,0). South 15→(0,−15). Left turn (S→E), East 10→(10,−15). Left turn (E→N), North 20→(10,5). Right turn (N→E), East 14→(24,5). Right turn (E→S), South 12→(24,−7). Distance = √(24²+7²) = √(576+49) = √625 = 25 km.
80. A man starts from a point facing North and walks 25 km. He turns right and walks 30 km. He turns right and walks 10 km. He turns right and walks 15 km. He turns right and walks 6 km. He turns right and walks 5 km. Find the distance between the starting point and his final position.
- (A) 41 km
- (B) 29 km
- (C) 19 km
- (D) 35 km
Answer: (B) 29 km
Explanation: (0,0). N25→(0,25). Right(N→E), E30→(30,25). Right(E→S), S10→(30,15). Right(S→W), W15→(15,15). Right(W→N), N6→(15,21). Right(N→E), E5→(20,21). Distance = √(20²+21²) = √(400+441) = √841 = 29 km. (Six legs, every turn to the right — track each coordinate change carefully.)
81. A man starts from a point facing North and walks 40 km. He turns left and walks 20 km. He turns left and walks 10 km. He turns left and walks 10 km. He turns left and walks 5 km. He turns left and walks 2 km. Find his distance from the starting point.
- (A) 47 km
- (B) 37 km
- (C) 27 km
- (D) 53 km
Answer: (B) 37 km
Explanation: (0,0). N40→(0,40). Left(N→W), W20→(−20,40). Left(W→S), S10→(−20,30). Left(S→E), E10→(−10,30). Left(E→N), N5→(−10,35). Left(N→W), W2→(−12,35). Distance = √(12²+35²) = √(144+1225) = √1369 = 37 km.
82. A man starts facing South and walks 4 km. He turns left and walks 6 km. He turns left and walks 4 km. He turns right and walks 8 km. He turns right and walks 3 km. Which direction is he facing at the end?
- (A) North
- (B) East
- (C) South
- (D) West
Answer: (C) South
Explanation: Facing only depends on the sequence of turns, not on the distances walked. Start South. Left (S→E). Left (E→N). Right (N→E). Right (E→S). After these four turns he is again facing South — the leg lengths (4,6,4,8,3 km) never had to be used at all.
83. A cyclist starts at point O facing West and rides 10 km. He turns right and rides 4 km. He turns right and rides 6 km. He turns left and rides 5 km. He turns left and rides 9 km. In which general direction is he from O now?
- (A) North-East
- (B) South-West
- (C) North-West
- (D) South-East
Answer: (C) North-West
Explanation: O=(0,0). West 10→(−10,0). Right(W→N), North 4→(−10,4). Right(N→E), East 6→(−4,4). Left(E→N), North 5→(−4,9). Left(N→W), West 9→(−13,9). Final point (−13,9) has negative x (West of O) and positive y (North of O), placing him in the North-West direction from O.
84. A man starts facing East and walks 2 km. He turns right and walks 3 km. He turns left and walks 2 km. He turns left and walks 15 km. He turns right and walks 1 km. Find his distance from the starting point.
- (A) 17 km
- (B) 9 km
- (C) 21 km
- (D) 13 km
Answer: (D) 13 km
Explanation: (0,0). East 2→(2,0). Right(E→S), South 3→(2,−3). Left(S→E), East 2→(4,−3). Left(E→N), North 15→(4,12). Right(N→E), East 1→(5,12). Distance = √(5²+12²) = √(25+144) = √169 = 13 km.
85. Starting from point Z facing North, a man walks 10 km, turns right, walks 9 km, turns right, walks 5 km, turns right, walks 5 km, turns right, walks 3 km, turns right, walks 2 km. Find the shortest distance from Z to his current position.
- (A) 10 km
- (B) 16 km
- (C) 6 km
- (D) 20 km
Answer: (A) 10 km
Explanation: Z=(0,0). N10→(0,10). Right(N→E), E9→(9,10). Right(E→S), S5→(9,5). Right(S→W), W5→(4,5). Right(W→N), N3→(4,8). Right(N→E), E2→(6,8). Distance = √(6²+8²) = √(36+64) = √100 = 10 km.
86. A man faces West. He makes three consecutive right turns (walking some distance after each). Which direction does he face after the third turn?
- (A) North
- (B) South
- (C) East
- (D) West
Answer: (B) South
Explanation: From West: right turn 1 → North; right turn 2 → East; right turn 3 → South. Three right turns (270°) from West land on South — regardless of how far he walked at each stage.
87. A man starts facing South and walks 5 km. He turns left and walks 6 km. He turns right and walks 4 km. He turns left and walks 3 km. He turns right and walks 3 km. Find his straight-line distance from the start, and the general direction of his final point.
- (A) 15 km, North-West
- (B) 15 km, South-East
- (C) 9 km, South-East
- (D) 21 km, South-West
Answer: (B) 15 km, South-East
Explanation: (0,0). South 5→(0,−5). Left(S→E), East 6→(6,−5). Right(E→S), South 4→(6,−9). Left(S→E), East 3→(9,−9). Right(E→S), South 3→(9,−12). Distance = √(9²+12²) = √(81+144) = √225 = 15 km. Final point (9,−12) is East and South of start, i.e. South-East.
88. A man walks 6 km North, 8 km East, 6 km South, 8 km West, and finally 6 km North again. Where is he now with respect to the starting point?
- (A) At the starting point
- (B) 8 km East
- (C) 6 km North
- (D) 14 km North
Answer: (C) 6 km North
Explanation: (0,0). N6→(0,6). E8→(8,6). S6→(8,0). W8→(0,0) — at this stage he is back at the start. But there is one more leg: N6→(0,6). His final position is 6 km North of the start — the trap is stopping the calculation one leg too early.
89. A man starts facing East from point O and walks 20 km. He turns right and walks 25 km. He turns right and walks 10 km. He turns right and walks 10 km. He turns right and walks 10 km. He turns right and walks 5 km. He turns right and walks 5 km. Find his distance from O and the general direction of his final position.
- (A) 25 km, North-West
- (B) 25 km, South-East
- (C) 35 km, South-East
- (D) 25 km, South-West
Answer: (B) 25 km, South-East
Explanation: O=(0,0). E20→(20,0). Right(E→S), S25→(20,−25). Right(S→W), W10→(10,−25). Right(W→N), N10→(10,−15). Right(N→E), E10→(20,−15). Right(E→S), S5→(20,−20). Right(S→W), W5→(15,−20). Distance = √(15²+20²) = √(225+400) = √625 = 25 km. Final point (15,−20) is East and South of O — South-East.
90. A man starts facing North from O and walks 10 km. He turns right and walks 5 km. He turns left and walks 8 km. He turns right and walks 7 km. He turns right and walks 2 km. Find (i) his distance from O and (ii) the direction he is now facing.
- (A) 20 km; facing North
- (B) 16 km; facing East
- (C) 20 km; facing South
- (D) 20 km; facing West
Answer: (C) 20 km; facing South
Explanation: O=(0,0). N10→(0,10). Right(N→E), E5→(5,10). Left(E→N), N8→(5,18). Right(N→E), E7→(12,18). Right(E→S), S2→(12,16). Distance = √(12²+16²) = √(144+256) = √400 = 20 km. Turn sequence N→E→N→E→S means his final facing direction is South.
9. Common Traps — A Consolidated List
This chapter gathers, in one place, every trap already raised across the earlier chapters, so you can do a final revision pass before an exam without re-reading the whole book.
9.1 Losing Track of Current Facing Direction
After three or more turns, students frequently apply a left/right turn to the ORIGINAL facing direction instead of the CURRENT one. The fix is mechanical: after every turn, physically write down (even in one word) the new facing direction before reading the next sentence.
9.2 Sign Errors in Coordinate Tracking
North and East should consistently be treated as positive, South and West as negative (or vice versa, as long as you are consistent throughout one question). A single sign flip partway through a long calculation silently produces a wrong final answer that still "looks" plausible.
9.3 Confusing Clockwise and Anticlockwise Turns
Clockwise (as viewed from above, i.e. a bird's-eye view of the map) is the same as a right turn; anticlockwise is the same as a left turn. When a question uses the words "clockwise" or "anticlockwise" instead of "left" or "right", immediately translate it into left/right using this equivalence before applying the turn-rule table.
9.4 "Turns to Face" vs. "Turns and Walks"
Some question sentences describe a pure change of orientation with no movement ("he turns to face East"), while others describe a turn immediately followed by a walk ("he turns right and walks 6 km"). Confusing the two causes students to either add a distance that was never walked, or to forget a movement that was described. Read each clause carefully for a distance figure before assuming movement has occurred.
9.5 Direction of A from B vs. B from A
The direction from the starting point to the final point is always the exact opposite of the direction from the final point back to the starting point. A large fraction of "trick" questions simply ask for the reverse of what a hasty reader assumes is being asked — always underline which point is the reference point before answering.
10. The Coordinate-Grid Framework — A Step-by-Step Checklist
This final theory chapter consolidates everything into one repeatable procedure. Follow these seven steps for every Direction Sense question, however simple or complex it looks:
Step 1: Treat the starting point as the origin (0, 0). Let North = +y, South = −y, East = +x, West = −x.
Step 2: Note the initial facing direction stated in the question (default to North if not stated and the question is purely about diagram-style movement).
Step 3: Process the movements one at a time, in order. For each movement, update the (x, y) position using the current facing direction and the distance given.
Step 4: For each turn (left, right, clockwise, anticlockwise, or a specific angle), update the current facing direction using the turn-rule table — before moving on to the next movement.
Step 5: At the end, separately total the net North-South value and the net East-West value (adding same-direction legs, subtracting opposite-direction legs).
Step 6: If the question asks for distance, apply the Pythagorean theorem to the two net values from Step 5 (skip this step entirely if one of the two net values is zero — then the distance is simply the other value).
Step 7: If the question asks for direction, read off the quadrant from the signs of the two net values (both positive = North-East, positive x/negative y = South-East, and so on), or, for a "facing direction" question, simply re-trace the turns using only Step 4 and ignore Steps 3, 5 and 6 entirely.
10.1 Fully Worked Examples Using the Complete Framework
Solved Example: Framework Example 1 — Distance and Direction Together
Question: A man starts facing East and walks 20 km. He turns left and walks 10 km. He turns left again and walks 20 km. He turns right and walks 5 km. He turns right again and walks 8 km. Find his distance from the starting point.
Step 1–2: O=(0,0); initial facing = East.
Step 3–4, Leg 1: East 20 → (20,0). Turn left: East→North.
Leg 2: North 10 → (20,10). Turn left: North→West.
Leg 3: West 20 → (0,10). Turn right: West→North.
Leg 4: North 5 → (0,15). Turn right: North→East.
Leg 5: East 8 → (8,15).
Step 5: Net North-South = 10+5 = 15 km North. Net East-West = 20−20+8 = 8 km East.
Step 6: Distance = √(8²+15²) = √(64+225) = √289 = 17 km.
Answer: 17 km.
Solved Example: Framework Example 2 — Facing Direction Only (Distances Ignored)
Question: A man starts facing South and walks 4 km. He turns left and walks 6 km. He turns left and walks 4 km. He turns right and walks 8 km. He turns right and walks 3 km. Which direction is he facing at the end?
Since only the final facing direction is asked, apply Step 4 alone and skip Steps 3, 5, 6.
Start: South. Turn left: South→East. Turn left: East→North. Turn right: North→East. Turn right: East→South.
Answer: He faces South at the end — exactly as he started, since the four turns (left, left, right, right) cancel out (2 lefts + 2 rights = net zero rotation).
Solved Example: Framework Example 3 — Shadow Question via the Same Framework
Question: In the evening, the shadow of a pole falls to Deepak's right. Which direction is Deepak facing?
This is a Direction Sense question in disguise — the framework still applies, but the "movement" here is the sun's position rather than a walked path.
Step A: Fix the absolute shadow direction using time of day: evening → sun in West → shadow in East (opposite the sun).
Step B: The shadow (East) is on Deepak's right-hand side, so his right hand currently points East.
Step C: Use the turn-rule table in reverse — find which facing direction has "right = East": facing North.
Answer: Deepak is facing North.
10.2 Diagram Description: The Complete 8-Direction Reference
Picture a plus-sign (+) with North at the top, East on the right, South at the bottom, and West on the left — this is your main cross. Now picture an X drawn through the same centre point, at 45° to the main cross: North-East is the upper-right diagonal arm, South-East is the lower-right arm, South-West is the lower-left arm, and North-West is the upper-left arm. Together the plus-sign and the X form an eight-pointed star — this is the complete compass rose used throughout this book, and it is worth sketching from memory until it becomes automatic.

12. Consolidated Answer Key with Brief Reasoning
| Q# | Answer | Brief Reasoning |
|---|---|---|
| 1 | (C) 10 km | Right triangle 6-8; √(36+64)=√100=10 km. |
| 2 | (D) 15 km | √(9²+12²)=√225=15 km (3-4-5 ×3). |
| 3 | (B) 7 km East | North and South legs (7,7) cancel; only East 7 remains. |
| 4 | (C) South | Two right turns = 180°: N→E→S. |
| 5 | (A) South | E→N(left)→W(left)→S(left); three lefts = 270°. |
| 6 | (B) East | North/South components cancel (equal legs); East components add → due East. |
| 7 | (B) 26 km | √(10²+24²)=√676=26 km (5-12-13 ×2). |
| 8 | (A) North | Morning shadow = West; left = West only when facing North. |
| 9 | (C) North | Evening shadow = East; right = East only when facing North. |
| 10 | (C) East | 3 is 90° clockwise from 12(North) → East. |
| 11 | (A) West | 9 is 270° clockwise from North → West. |
| 12 | (D) North-East | C lies both North and East of A → North-East quadrant. |
| 13 | (D) East | Facing North, right hand = East, so X is East of Y. |
| 14 | (D) At the starting point | North/South (8,8) cancel and East/West (6,6) cancel — a closed rectangle, back to start. |
| 15 | (D) 15 km | √(9²+12²)=√225=15 km. |
| 16 | (D) 29 km | √(20²+21²)=√841=29 km. |
| 17 | (D) 13 km, South-West | √(5²+12²)=13 km; West+South legs → South-West quadrant. |
| 18 | (D) West | Evening shadow = East; 'behind' means facing opposite of East, i.e. West. |
| 19 | (B) 14 km East | (0,0)→N12→(0,12)→E5(R)→(5,12)→S12(R)→(5,0)→E9(L)→(14,0): 14 km East. |
| 20 | (D) North | East/West components cancel; North components (equal) add → due North. |
| 21 | (D) East | Facing South, left hand = East, so P is East of Q. |
| 22 | (B) 25 km | √(15²+20²)=√625=25 km. |
| 23 | (C) 20 km | √(16²+12²)=√400=20 km. |
| 24 | (B) East | W→N(right)→E(right); two rights = 180° reversal of West = East. |
| 25 | (C) East | Evening sun = West; sun behind means facing opposite, i.e. East. |
| 26 | (C) 8 km East | North(3)/South(3) cancel; East legs add: 4+4=8 km East. |
| 27 | (D) 30 km | √(18²+24²)=√900=30 km. |
| 28 | (B) East | Facing the centre from the West side means facing East. |
| 29 | (D) North-East | A 45° right (clockwise) turn from North lands exactly on North-East. |
| 30 | (B) 24 km, East | (0,0)→S7→(0,-7)→E24(left,S→E)→(24,-7)→N7(left,E→N)→(24,0). South legs (7,7) cancel; distance = 24 km due East. |
Final Word
Direction Sense rewards a calm, methodical approach far more than it rewards raw speed. A student who takes an extra ten seconds to draw a coordinate grid will consistently outperform one who tries to hold five turns in their head. Revise the turn-rule table, the Pythagorean triples table, and the sun-shadow table from this book until you can reproduce them without thinking, and this topic will become one of the most reliably scoring sections of your paper.
