Question

Fifteen years from now Ravi’s age will be four times his present age. What is Ravi’s present age?

Answer 1

Finding Ravi's age

Let the present age of Ravi be $x$.

Fifteen years later, Ravi's age will be $x+15$ years which is given same as four times his present age i.e.,

$$\begin{gathered} x+15=4x \\ \Rightarrow 3x=15 \\ \Rightarrow x=5 \end{gathered}$$

Therefore, Ravi's present age is $5$
