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 22, then how old is B? Pick one.
A) 7  B) 8  C) 9  D) 10  E) 11
Let C's age be x years.   Then, B's age = 2x years.   A's age = (2x + 2) years.   (2x + 2) + 2x + x = 22   5x = 20 =&gt; x = 4   Hence, B's age = 2x = 8 years.   ANSWER:8
