Answer 1

$\textbf{\huge{HALLO! }}$

Here's your answer:

Let Binu's age be x,

Let Manu's age be 6x.

15 years hence,

Binu's age will be =x +15

Manu's age will be =6x+15

Manu will be 3 times old than Binu.

By putting this in an equation & solving it...

6x + 15 = 3×(x+15).

6x + 15 = 3x + 45

6x - 3x = 45 - 15

3x = 30

$\fbox{X=10}$

Answer: Binu is 10 years old.

Hope this cleared your doubt ☺
