Question 91

Solve the following:

After 12 years, Kanwar shall be 3 times as old as he was 4 years ago. Find his present age.

Answer 1

Let Kanwar's present age be x yr.
After 12 yr, Kanwar's age=(x+12) yr.
and 4 yr ago, Kanwar's age =(x-4) yr.
According to the question,
$x+12=3(x-4)\Rightarrow x+12=3x-12\Rightarrow 3x-x=12+12\Rightarrow 2x=24\Rightarrow x=\frac{24}{2}\therefore x=12$
Hence, Kanwar's present age is 12 yr.
