Question

Mayank is thrice as old as Akash. After five years he will be twice as old as Akash. Find their present ages. The sum of present age is $20$ years.

Answer 1

Let the ages of Mayank and Akash be $M,A$ respectively

Given that

$\Rightarrow M=3A$ and

$\Rightarrow M+5=2(A+5)$

$\Rightarrow M+5=2A+10$

$\Rightarrow 3A+5=2A+10$

$\Rightarrow A=5$

$\Rightarrow M=3A=3\left(5\right)=15$

$\Rightarrow A=5,M=15$
