Question

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

• A. $5$
• B. $8$
• C. $7$
• D. $3$

Answer 1

The correct option is A $5$

Let Ravi's present age be $x$ years.

After $15$ years, his age will be $(x+15)$ years.
It is given that after $15$ years, Ravi's age will be four times his present age.

$\therefore 4x=x+15$
$\Rightarrow 4x-x=15$

$\Rightarrow 3x=15$

$\Rightarrow x=\frac{15}{3}=5$

Hence, Ravi's present age is $5$ years.
