Step-by-step explanation:

Given :

Age Of Manoj after 12 years = 3x

Age Of Manoj 4 years ago

Find :

Present Age Of Manoj

Solution :

Let Manoj Present age be X years

Manoj age after 12 years will be X + 12

Manoj age before 4 years was X - 4

According to Questions

X + 12 = 3 ( X - 4 )

X + 12 = 3x - 12

3x - x = - 12 - 12 ( Variable and Digit each other side )

2x = 24

X = 24/2

X = 12

The Present age of Manoj is 12 years
