Answer Key with Explanations

Section A:

1.(a) Q is R's brother and S is R's daughter, so Q is S's uncle; since P is Q's mother, P is S's grandmother.

2.(b) Using the Pythagorean theorem: distance = √(6² + 8²) = √(36+64) = √100 = 10 km.

3.(a) Each letter shifts forward by one place in the alphabet, the same rule as HOUSE→IPVTF; applying it to MOUSE gives NPVTF.

4.(a) Since X < Y ≤ Z < W, it follows directly that W > X.

5.(a) The gaps between letters increase: C to F is +3, F to J is +4, J to O is +5, so O to next is +6, giving U.

6.(b) No, this does not necessarily follow: the "some records" that are audited may not include any accounts specifically.

7.(b) With 9 floors, the middle floor is floor 5.

8.(a) Rank from the bottom = 45 − 18 + 1 = 28th.

9.(a) Each term follows ×2+1: 6×2+1=13, 13×2+1=27, 27×2+1=55, 55×2+1=111.

10.(a) Substituting the coded meanings and applying standard order of operations: 8 + 5 − (3 × 2) = 13 − 6 = 7.

11.(a) Arranging from the clues, the order is: C, E, D, B, A, placing C at one end and A at the other.

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

13.(a) Each letter shifts forward by one place in the alphabet, the same rule as RIVER→SJWFS; applying it to OCEAN gives PDFBO.

14.(a) Yes, this follows validly: all loans are financial products, and no financial products are free, so no loan can be free.

15.(a) Position from the right = 42 − 17 + 1 = 26th.

16.(a) Let B's present age be x and A's be 3x; six years ago, 3x−6 = 5(x−6), giving 3x−6 = 5x−30, so 2x=24, x=12; B's present age is 12 years.

17.(a) Each term follows ×2+2: 3×2+2=8, 8×2+2=18, 18×2+2=38, 38×2+2=78.

18.(a) Starting from North, turning 90° anticlockwise gives West, and a further 90° anticlockwise gives South.

19.(a) Each letter is coded by its position in the alphabet; applying the same code, MUMBAI is written as 13-21-13-2-1-9.

20.(b) No, this does not necessarily follow: the "some documents" that are forged may not include any cheques specifically.

Section B:

21.(a) 48 ÷ 8 + 9 × 2 − 4 = 6 + 18 − 4 = 20.

22.(a) Interest earned = 25,000 − 20,000 = 5,000; rate = (5,000×100)/(20,000×2) = 12.5%.

23.(a) Let cost price be x; 0.88x + 240 = 1.08x, giving 240 = 0.20x, so x = 1,200.

24.(a) Let the numbers be 4y and 7y; 4y+7y=121, so 11y=121, y=11; the larger number is 7×11=77.

25.(a) CI = 30,000 × (1.1)² − 30,000 = 30,000×1.21 − 30,000 = 36,300−30,000 = ₹6,300.

26.(a) Combined rate = 1/18; A's rate = 1/30; B's rate = 1/18 − 1/30 = 5/90 − 3/90 = 2/90 = 1/45; B alone takes 45 days.

27.(a) Combined rate = 1/12 + 1/18 = 3/36 + 2/36 = 5/36; time taken together = 36/5 = 7.2 hours.

28.(a) Increase = 520 − 400 = 120; percentage increase = (120/400) × 100 = 30%.

29.(a) 6(x−4) = 3x+3 → 6x−24 = 3x+3 → 3x = 27 → x = 9.

30.(a) Area = πr² = (22/7) × 21 × 21 = 22 × 3 × 21 = 1,386 sq cm.

31.(a) Sum of six numbers = 6×30 = 180; sum of remaining five = 5×28 = 140; excluded number = 180−140 = 40.

32.(a) If a sum doubles in 8 years, the rate is 100%/8 = 12.5% per annum.

33.(a) Let cost price be 100; marked price = 150; selling price after 20% discount = 150×0.8 = 120; profit percentage = 20%.

34.(a) Total investment = 30,000+40,000+50,000 = 1,20,000; largest partner's share = (50,000/1,20,000) × 60,000 = ₹25,000.

35.(a) (225÷15)×4+15 = 15×4+15 = 60+15 = 75.

36.(a) Upstream speed = 18−6 = 12 km/h; time = 96/12 = 8 hours.

37.(a) If the cost price of 15 articles equals the selling price of 12, the trader gains the value of 3 extra articles per 12 sold; profit percentage = (3/12)×100 = 25%.

38.(a) Interest for 1 year (year 2 to 3) = 14,000−12,600 = 1,400; interest for 2 years = 2,800; principal = 12,600−2,800 = ₹9,800.

39.(a) The differences between terms decrease: 120−108=12, 108−97=11, 97−87=10, so the next difference is 9, giving 87−9=78.

40.(a) Let B's share be x; A's share = 1.25x; x+1.25x = 24,000, so 2.25x=24,000, x ≈ 10,666.67.

Section C:

41.(a) Correct: "Neither of the two schemes has been approved" — "neither" takes a singular verb.

42.(a) Correct: "If interest rates were lower, more people would take loans" — the second conditional (unreal present) requires "were" in the if-clause.

43.(a) "credited with ₹5,000" is correct.

44.(a) Prudent means wise and careful in practical matters, matching "Wise."

45.(b) Solvent means able to pay debts; its antonym is "Insolvent."
