Answer 1

Answer:

C. F oldest and D youngest

Let A's age be x. B is twice as old as A -----> B's age is 2x. B is twice younger than F i.e. F is twice older than B. So, F's age is 4x. C is half the age of A i.e. C's age is x/2. C is twice the age of D i.e D is half the age of C i.e. D's age is x/4. descending order of ages will be F, B, A, C, D. F is the oldest and D is the youngest.
