Question

After 12 years Manoj will be 3 times as old as he was 4 years ago. Find his present age.​

Answer 1

Step-by-step explanation:

Let the present age of manoj be x years.

After 12 years his age=x+12

4 years ago his age=x-4

from the given condition,

x+12=3(x-4)

x+12=3x-12

x-3x= -12-12

-2x= -24

x= -24/-2

x=12

Therefore,the present age of manoj is 12 years old.
