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?
Choose the correct choice from the following answers
A) 7 years.	B) 8 years.	C) 9 years.	D) 10 years.	E) 11 years.
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.   Answer 10 years.
