Q
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??
AA. 7
BB. 8
CC. 9
DD. 10
Correct Answer:
D. D. 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 = 27
⇒ 5x = 25
⇒ x = 5.
Hence, B’s age = 2x = 10 years.
