Step-by-step explanation:
Let the present ages = x
The ages of Hari and Harry are in the ratio =5:7
The Hari and Harry ages will be = 5x and 7x years
Four years later, the ages will be
(5x+4) and ( 7x+4 )
- 4( 5x+4 ) = 3( 7x+4 )
- 20x+16 = 21x+12
- 16-12 = 21x-20x
- x = 4×1
- x=4
The present age of Hari = 5×4=20 years.
The present age of Harry = 7×4=28 years.
I hope it helps you!
