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

1. 5
2. 8
3. 10
4. 12
5. 14

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.
