A is two years older than B who is twice as old as C. If the total of the ages of A, B and C be 27, the how old is B?

A10

B9

C8

D7

Answer:

A. 10

Read Explanation:

Let C's age be x years. Then, B's age = 2x years. A's age = (2x + 2) years. ∴ (2x + 2) + 2x + x = 27 ⇒ 5x = 25 ⇒ x = 5. Hence, B's age = 2x = 10 years
