Answer 2

Answer:

Hari = 20 years ,and Harry = 28 years

Step-by-step explanation:

Let their ages be 5x and 7x

so ,their ages after 4 years :

•Hari = 5x +4

•Harry= 7x +4

BTP,

5x+4 / 7x+4 = 3/4

=>20x +16 = 21x +12

=>20x-21x = 12-16

=>-1x = -4

=>x = 4

so ,Hari's present age = 5x

= 5*4

=20 years

and, Harry's present age = 7x

=7*4

=28 years
