Answer 1

hey
______________________________

Let the present age of Hari be 5x years
So, the present age of Harry be 7x years

A.T.Q.

5x+4/7x+4 = 3/4
=> 4(5x+4) = 3(7x+4)
=> 20x+16 = 21x+12
=> 20x-21x = 12-16
=> -x = -4
=> x = 4

♦ Present age of Hari
= 5x years
= 5×4 years
= 20 years

♦ Present age of Harry
= 7x years
= 7×4 years
= 28 years
