Question

A is 2 years older than B who is twice as old as C If the total of the ages of A, B and C be 27 years then how old is B?

• A. 7 years
• B. 8 years
• C. 9 years
• D. 10 years

Answer 1

Answer: (D)

10 years

Let C' age $=x$ years Then
B's age $=2x$ years
As age $(2x+2)$ years
Given $(2x+2)$ years
$\Rightarrow 5x+2=27\Rightarrow 5x=25\Rightarrow x=5$
$\therefore$ B's age $=(2\times 5)$ years $=10$ years.
