Question

After 12 year, Raju shall be three times as old as he was 4 years ago find his present age ?

Answer 1

Let the present age of Raju be x years.

Four years ago his age was = x - 4 years.

As per given condition:-

$x + 12 = 3 \: (x - 4) \\ \\ x + 12 = 3x - 12 \\ \\ 12 + 12 = 3x - x \\ \\ 24 = 2x \\ \\ x = \frac{24}{2} \\ \\ x = 12 \: years$

So present age of Raju is 12 years.
