# After 20 years, Manoj will be 5 times as old as he is now. Find his present age.

Let the Manoj’s present age be x yr.

Then, Manoj’s age after 20 yr = (x + 20) yr.

It is given that after 20 yr, Manoj’s age will be 5 times his present age.

Therefore, the equation is x + 20 = 5x

20 = 5x – x

20 = 4x

[Divide by 4 both sides]

5 = x

Hence, the present age of Manoj is 5 yrs.
