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, then how old is B ?


A) 7

B) 8

C) 9

D) 10

E) 11

Answer:

Option D

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
