Answer 2

Step-by-step explanation:

hope it will help

let Hari age be x year

and Hari father age = 2x

Twenty years ago Hari age = x - 20

Twenty years ago Hari father age = 2x - 20

A.T.Q

4 ( x - 20 ) = 2x - 20

4x - 80 = 2x - 20

4x - 2x = 80 - 20

2x = 60

x = 60 / 2

x = 30 year of Hari age

Hari father age = 2x

= 2 * 30

= 60 year
