Answer:
Let the present age of Manoj be x ; then Manoj's age after 20 years will be (x + 20) years.
According to the question :
(x + 20) = 5 × x
x + 20 = 5x
20 = 5x - x
20 = 4x
20/4 = x
5 = x
__________________________
Thus the present age of Manoj is 5 years.
A᭄nswer:- Manoj is 5 years old.

⇒ x= 4/20
⇒ x=5
Therefore, Manoj is 5 years old.
