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?
Choose the correct option.
A) 17 years B) 19 years C) 29 years D) 10 years E) 12 years
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 =&gt; x = 5   Hence, B's age = 2x = 10 years.   Answer: 10 years
