Answer:

Present age of Manoj is 12 years

Step-by-step explanation:

Let the age of Manoj be x years

Age of Manoj 4 years ago=x-4

Age of Manoj after 12 years=x+12

According to the question

After 12 years age of Manoj =3(x-4)

x+12=3(x-4)

x+12=3x-12

12+12=3x-x

2x=24

x=24/2

x=12 years

Answer 2

let the age of he was x

and the age of Manoj be 3x

after 12 years Manoj will be 3 times as old as he so,

4 x + 12 - x + 12 =0

2x + 24 = 0

x= 12

age of he was 12 year and the age of Manoj was 36 year
