Question

Q29. Who among the following is the oldest person?

1. A. E
2. B. B (Correct answer)
3. C. G
4. D. D
5. E. None of these

Correct Answer

Option B — B

Detailed Solution & Explanation

The correct answer is Option B.

Key Points

• Puzzle setup: seven people born in 1947, 1959, 1964, 1973, 1978, 1988, 2001 (ages in 2025: 78, 66, 61, 52, 47, 37, 24).
• Applying the clues — C + F = D, G divisible by 6, A + G prime, A just older than F, A + B divisible by 5 — fixes the arrangement as B = 1947 (78), G = 1959 (66), D = 1964 (61), E = 1973 (52), A = 1978 (47), F = 1988 (37), C = 2001 (24).
• The oldest person is the one born earliest — in 1947, aged 78 — which from the grid is B.
• the earliest birth year gives the greatest age; do not let the year (1947 being the smallest number) confuse you into picking it as 'youngest'.
• Oldest = smallest birth year = largest age.

Exam Tip

• a classic trap in birth-year puzzles is mixing up 'oldest' and 'youngest' — always translate to age first, where the ordering is intuitive (78 > 66 > … > 24).
