### Question

**A is two years older than B who is twice as old as C. The total of the ages of A, B and C is 27. How old is B?**

A. 7

B. 8

C. 9

D. 10

#### Answer: D. 10

**Solution:**

Let age of C = x

age of B = 2x

age of A = 2 + 2x

Total age of A,B and C = 27

⇒ (2 + 2x) + 2x + x = 27

⇒ 5x = 25

⇒ x = 25/5 = 5

**B’s age** = 2x = 2 × 5 **= 10**

Hence, The answer is **10**.
