Answer Key with Explanations

Section A:

1.(a) D is C's husband, and A is B's grandfather with C being B's mother, so A is C's father; since D is C's husband, A is D's father-in-law.

2.(a) Using the Pythagorean theorem: distance = √(16² + 30²) = √(256+900) = √1156 = 34 km.

3.(a) Each letter shifts forward by one place in the alphabet, the same rule as WATER→XBUFS; applying it to FRIEND gives GSJFOE.

4.(a) Since K ≤ L < M ≤ N, it follows directly that N ≥ K.

5.(a) The gaps between letters increase: L to P is +4, P to U is +5, U to A is +6 (wrapping past Z), so the next gap is +7; A is the 1st letter, +7 gives the 8th letter, H.

6.(a) Cannot be determined: the "some insurance-cum-investment products" that have a lock-in period may or may not include ULIPs specifically.

7.(a) With 25 floors, the middle floor is floor 13.

8.(a) Rank from the bottom = 100 − 44 + 1 = 57th.

9.(a) Each term follows ×2−1: 4×2−1=7, 7×2−1=13, 13×2−1=25, 25×2−1=49.

10.(a) Substituting the coded meanings and applying standard order of operations: 35 + 12 − (8 × 4) = 47 − 32 = 15.

11.(a) Arranging from the clues, the order is: K, L, M, N, O, placing K at one end and O at the other.

12.(a) A is B's father'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 shifts forward by one place in the alphabet, the same rule as PENCIL→QFODJM; applying it to ERASER gives FSBTFS.

14.(a) Yes, this follows validly: all hybrid mutual funds are investment vehicles, and no investment vehicles are entirely risk-free, so no hybrid mutual fund can be entirely risk-free.

15.(a) Position from the right = 70 − 32 + 1 = 39th.

16.(a) Let B's present age be x and A's be 10x; eight years ago, 10x−8 = 19(x−8), giving 10x−8 = 19x−152, so 9x = 144, x = 16; B's present age is 16 years.

Section B:

21.(a) 132÷12+24×2−15 = 11+48−15 = 44.

22.(a) Interest earned = 58,500−45,000 = 13,500; rate = (13,500×100)/(45,000×3) = 10%.

23.(a) Let cost price be x; 0.68x+960 = 1.04x, giving 960 = 0.36x, so x ≈ 2,666.67.

24.(a) Let the numbers be 12y and 23y; 12y+23y=245, so 35y=245, y=7; the larger number is 23×7=161.

25.(a) CI = 1,20,000×(1.05)²−1,20,000 = 1,20,000×1.1025−1,20,000 = 1,32,300−1,20,000 = ₹12,300.

26.(a) Combined rate = 1/60; A's rate = 1/100; B's rate = 1/60−1/100 = 5/300−3/300 = 2/300 = 1/150; B alone takes 150 days.

27.(a) Combined rate = 1/32+1/48 = 3/96+2/96 = 5/96; time taken together = 96/5 = 19.2 hours.

28.(a) Increase = 105−70 = 35; percentage increase = (35/70)×100 = 50%.

29.(a) 14(x−9)=10x+6 → 14x−126=10x+6 → 4x=132 → x=33.

30.(a) Area = πr² = (22/7)×70×70 = 22×10×70 = 15,400 sq cm.

31.(a) Sum of fourteen numbers = 14×70=980; sum of remaining thirteen = 13×68=884; excluded number = 980−884=96.

32.(a) If a sum doubles in 10 years, the rate is 100%/10 = 10% per annum.

33.(a) Let cost price be 100; marked price=400; selling price after 70% discount = 400×0.30=120; profit percentage=20%.

34.(a) Total investment = 1,20,000+1,30,000+1,40,000=3,90,000; largest partner's share = (1,40,000/3,90,000)×1,95,000 = ₹70,000.

35.(a) (1,000÷50)×7+55 = 20×7+55 = 140+55 = 195.

36.(a) Upstream speed = 45−9=36 km/h; time = 108/36 = 3 hours.

37.(a) If the cost price of 50 articles equals the selling price of 40, the trader gains the value of 10 extra articles per 40 sold; profit percentage = (10/40)×100 = 25%.

38.(a) Interest for 1 year (year 2 to 3) = 49,500−45,000 = 4,500; interest for 2 years = 9,000; principal = 45,000−9,000 = ₹36,000.

39.(a) The differences between terms decrease: 500−450=50, 450−402=48, 402−356=46, so the next difference is 44, giving 356−44=312.

40.(a) Let B's share be x; A's share = 2.5x; x+2.5x=56,000, so 3.5x=56,000, x=16,000.

Section C:

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

42.(a) Correct: "If the FDI cap had been raised, more foreign investment would have flowed in" — the third conditional requires the past perfect in the if-clause.

43.(a) "invoice was raised against the client" is correct.

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

45.(a) Liquidity means the ability to convert assets to cash quickly; its antonym is "Illiquidity."

46.(a) "conversant with international trade regulations" is correct.

47.(a) Correct: "The delegation has expressed its concerns" — "delegation" as a single body takes "has."
