Answer Key with Explanations

Section A:

1.(a) H is I's sister, and I is J's son, so H is J's aunt; since G is H's father, G is J's grandfather.

2.(a) Using the Pythagorean theorem: distance = √(7² + 24²) = √(49+576) = √625 = 25 km.

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

4.(a) Since E < F ≤ G < H, it follows directly that H > E.

5.(a) The gaps between letters increase: H to L is +4, L to Q is +5, Q to W is +6, so W to next is +7; W is the 23rd letter, +7 gives the 30th position, which wraps around the 26-letter alphabet to the 4th letter, D.

6.(a) Cannot be determined: the "some deposits" that are tax-saving may or may not include FDs specifically.

7.(a) With 17 floors, the middle floor is floor 9.

8.(a) Rank from the bottom = 75 − 30 + 1 = 46th.

9.(a) Each term follows ×2+1: 3×2+1=7, 7×2+1=15, 15×2+1=31, 31×2+1=63.

10.(a) Substituting the coded meanings and applying standard order of operations: 18 + 6 − (4 × 2) = 24 − 8 = 16.

11.(a) Arranging from the clues, the order is: P, Q, R, S, T, placing P at one end and T at the other.

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

13.(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.

14.(a) Yes, this follows validly: all post office schemes are savings instruments, and no savings instruments are high-risk, so no post office scheme can be high-risk.

15.(a) Position from the right = 52 − 23 + 1 = 30th.

16.(a) Let B's present age be x and A's be 6x; five years ago, 6x−5 = 11(x−5), giving 6x−5 = 11x−55, so 5x = 50, x = 10; B's present age is 10 years.

17.(a) Each term follows ×2+1: 2×2+1=5, 5×2+1=11, 11×2+1=23, 23×2+1=47.

18.(a) Starting from West, turning 90° clockwise gives North, and a further 180° 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.(a) Yes, this follows validly: all NBFCs are financial institutions, and all financial institutions are regulated, so all NBFCs must be regulated.

Section B:

21.(a) 81÷9+16×2−10 = 9+32−10 = 31.

22.(a) Interest earned = 36,400−28,000 = 8,400; rate = (8,400×100)/(28,000×3) = 10%.

23.(a) Let cost price be x; 0.78x+500 = 1.03x, giving 500 = 0.25x, so x = 2,000.

24.(a) Let the numbers be 8y and 13y; 8y+13y=168, so 21y=168, y=8; the larger number is 13×8=104.

25.(a) CI = 70,000×(1.1)²−70,000 = 70,000×1.21−70,000 = 84,700−70,000 = ₹14,700.

26.(a) Combined rate = 1/36; A's rate = 1/60; B's rate = 1/36−1/60 = 5/180−3/180 = 2/180 = 1/90; B alone takes 90 days.

27.(a) Combined rate = 1/18+1/27 = 3/54+2/54 = 5/54; time taken together = 54/5 = 10.8 hours.

28.(a) Increase = 280−200 = 80; percentage increase = (80/200)×100 = 40%.

29.(a) 10(x−5)=6x+2 → 10x−50=6x+2 → 4x=52 → x=13.

30.(a) Area = πr² = (22/7)×42×42 = 22×6×42 = 5,544 sq cm.

31.(a) Sum of ten numbers = 10×50=500; sum of remaining nine = 9×48=432; excluded number = 500−432=68.

32.(a) If a sum doubles in 40 years, the rate is 100%/40 = 2.5% per annum.

33.(a) Let cost price be 100; marked price=220; selling price after 40% discount = 220×0.60=132; profit percentage=32%.

34.(a) Total investment = 70,000+80,000+90,000=2,40,000; largest partner's share = (90,000/2,40,000)×1,20,000 = ₹45,000.

35.(a) (450÷25)×6+35 = 18×6+35 = 108+35 = 143.

36.(a) Upstream speed = 26−4=22 km/h; time = 88/22 = 4 hours.

37.(a) If the cost price of 30 articles equals the selling price of 24, the trader gains the value of 6 extra articles per 24 sold; profit percentage = (6/24)×100 = 25%.

38.(a) Interest for 1 year (year 2 to 3) = 29,700−27,000 = 2,700; interest for 2 years = 5,400; principal = 27,000−5,400 = ₹21,600.

39.(a) The differences between terms decrease: 300−270=30, 270−242=28, 242−216=26, so the next difference is 24, giving 216−24=192.

40.(a) Let B's share be x; A's share = 1.6x; x+1.6x=48,000, so 2.6x=48,000, x≈18,461.54.

Section C:

41.(a) Correct: "Each of the depositors has received a receipt" — "each" takes a singular verb.

42.(a) Correct: "If the branch had been closed earlier, customers would have been informed" — the third conditional requires the past perfect in the if-clause.

43.(a) "charged with overdraft fees" is correct.
