Answer Key with Explanations

Section A:

1.(a) N is O's sister, and O is P's son, so N is P's aunt; since M is N's father, M is P's grandfather.

2.(a) Using the Pythagorean theorem: distance = √(9² + 12²) = √(81+144) = √225 = 15 km.

3.(a) Each letter shifts forward by one place in the alphabet, the same rule as LIGHT→MJHIU; applying it to DARK gives EBSL.

4.(a) Since A ≤ B < C ≤ D, it follows directly that D ≥ A.

5.(a) The gaps between letters increase: A to D is +3, D to H is +4, H to M is +5, so M to next is +6, giving S.

6.(a) Cannot be determined: the "some negotiable instruments" that are transferable may or may not include cheques specifically.

7.(a) With 11 floors, the middle floor is floor 6.

8.(a) Rank from the bottom = 50 − 22 + 1 = 29th.

9.(a) Each term follows ×2+1: 7×2+1=15, 15×2+1=31, 31×2+1=63, 63×2+1=127.

10.(a) Substituting the coded meanings and applying standard order of operations: 10 + 6 − (4 × 3) = 16 − 12 = 4.

11.(a) Arranging from the clues, the order is: T, U, V, W, X, placing T at one end and X at the other.

12.(a) A is B's mother's son, meaning A is B's brother; since C is B's sister, A and C are siblings, making A C's brother.

13.(a) Each letter is coded by its position in the alphabet; applying the same code, MOON is written as 13-15-15-14.

14.(a) Yes, this follows validly: all fixed deposits are investments, and no investments are absolutely risk-free, so no fixed deposit is absolutely risk-free.

15.(a) Position from the right = 38 − 15 + 1 = 24th.

16.(a) Let B's present age be x and A's be 4x; eight years ago, 4x−8 = 10(x−8), giving 4x−8 = 10x−80, so 6x=72, x=12; B's present age is 12 years.

17.(a) Each term follows ×2+2: 4×2+2=10, 10×2+2=22, 22×2+2=46, 46×2+2=94.

18.(a) Starting from South-West, turning 90° clockwise gives North-West.

19.(a) Each letter is coded by its position in the alphabet; applying the same code, FIELD is written as 6-9-5-12-4.

20.(a) Yes, this follows validly: all bonds are debt instruments, and all debt instruments carry interest, so all bonds must carry interest.

Section B:

21.(a) 56÷7+10×2−6 = 8+20−6 = 22.

22.(a) Interest earned = 23,400−18,000 = 5,400; rate = (5,400×100)/(18,000×3) = 10%.

23.(a) Let cost price be x; 0.85x+300 = 1.10x, giving 300 = 0.25x, so x = 1,200.

24.(a) Let the numbers be 5y and 8y; 5y+8y=130, so 13y=130, y=10; the larger number is 8×10=80.

25.(a) CI = 40,000×(1.15)²−40,000 = 40,000×1.3225−40,000 = 52,900−40,000 = ₹12,900.

26.(a) Combined rate = 1/20; A's rate = 1/35; B's rate = 1/20−1/35 = 7/140−4/140 = 3/140; B alone takes 140/3 ≈ 46.67 days.

27.(a) Combined rate = 1/9+1/12 = 4/36+3/36 = 7/36; time taken together = 36/7 ≈ 5.14 hours.

28.(a) Decrease = 800−600 = 200; percentage decrease = (200/800)×100 = 25%.

29.(a) 7(x−2)=3x+10 → 7x−14=3x+10 → 4x=24 → x=6.

30.(a) Area = πr² = (22/7)×7×7 = 22×7 = 154 sq cm.

31.(a) Sum of seven numbers = 7×35=245; sum of remaining six = 6×33=198; excluded number = 245−198=47.

32.(a) If a sum doubles in 20 years, the rate is 100%/20 = 5% per annum.

33.(a) Let cost price be 100; marked price=160; selling price after 25% discount = 160×0.75=120; profit percentage=20%.

34.(a) Total investment = 40,000+50,000+60,000=1,50,000; largest partner's share = (60,000/1,50,000)×75,000 = ₹30,000.

35.(a) (256÷16)×3+25 = 16×3+25 = 48+25 = 73.

36.(a) Downstream speed = 20+4=24 km/h; time = 96/24 = 4 hours.

37.(a) If the cost price of 18 articles equals the selling price of 15, the trader gains the value of 3 extra articles per 15 sold; profit percentage = (3/15)×100 = 20%.

38.(a) Interest for 1 year (year 2 to 3) = 17,800−16,200 = 1,600; interest for 2 years = 3,200; principal = 16,200−3,200 = ₹13,000.

39.(a) The differences between terms decrease: 150−135=15, 135−121=14, 121−108=13, so the next difference is 12, giving 108−12=96.

40.(a) Let B's share be x; A's share = 1.5x; x+1.5x=30,000, so 2.5x=30,000, x=12,000.

Section C:

41.(a) Correct: "Each of the branches has exceeded its target" — "each" takes a singular verb.

42.(a) Correct: "If the RBI cuts the rate, borrowing costs would fall" — a first conditional pairs a present-tense if-clause with a "would" main clause in this hypothetical framing common to exam usage.

43.(a) "flagged for suspicious activity" is correct.

44.(a) Diligent means showing care in one's work, matching "Hardworking."

45.(a) Prudent means wise and cautious; its antonym is "Reckless."

46.(a) "proficient in financial analysis" is correct.

47.(a) Correct: "The staff were unanimous in their decision" — when referring to individual members acting collectively with "their," "staff" should take the plural "were" for consistency.

49.(a) "Necessary" is the correctly spelled word, with one "c" and two "s"s.
