97. B is twice as old as A but twice younger than F. C is half the age of A but is twice older than D. Who is the second oldest?
(A) B
(B) F
(C) C
(D) D
Answer:
(A) B
Explanation:
Let’s assign an arbitrary value to the youngest person, D. If D = 1 year old: C is twice older than D, so C = 2. C is half the age of A, so A = 4. B is twice as old as A, so B = 8. B is twice younger than (half the age of) F, so F = 16. Ranking them by age: F (16), B (8), A (4), C (2), D (1). The second oldest is B.
