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 37, the how old is B?	Choose the correct answer:
A) 7 B) 9 C) 8 D) 14 E) 10
Explanation:   Let C's age be x years. Then, B's age = 2x years. A's age = (2x + 2) years.   (2x + 2) + 2x + x = 37   ⇒ 5x = 35   ⇒ x = 7.   Hence, B's age = 2x = 14 years.   Answer: 14
