Expert Answer

Given:

Mahesh's age = 20 years

His father's age = 50 years

Assume that x years ago Mahesh's father is 4 times as old as Mahesh.

Therefore Mahesh's age then = 20 - x and his father's age = 50 - x

According to the condition in the Question, we get

4(20 - x) = 50 -x

after solving, we get

x = 10

Therefore 10 years ago Mahesh's father is 4 times as old as Mahesh.
