Answer 1

Let Ravi’s present age be x years.

After fifteen years, Ravi’s age = 4x years.

Fifteen years from now, Ravi’s age = (x+15) years.

According to question, 4x = x + 15

$\Rightarrow\ 4x-x=15$

[Transposing x to L.H.S]

3x = 15

$\Rightarrow\ \frac{3x}{3}=\frac{15}{3}$

[Dividing both sides by 3]

x = 5 years.

Hence, Ravi’s present age be 5 years.
