Fifteen years from now Ravi's age will be four times his present age. What is Ravi's present age?
Given :
Fifteen years from now Ravi's age will be four times his present age.
To do :
We have to find Ravi's present age.
Solution :
Let the present age of Ravi be x.
Age of Ravi after 15 years $= x+15$
Therefore,
$4(x) = x+15$
$4x = x+15$
$4x-x = 15$
$3x = 15$
$x = \frac{15}{3}$
$x = 5$
The present age of Ravi is 5 years.
