Step-by-step explanation:

Let the age of Hari be 5x and Harry be 7x.

4 years later,

Age of Hari = 5x + 4

Age of Harry = 7x + 4

According to the question,

\frac{5 x+4}{7 x+4}=\frac{3}{4}

⇒ 4(5x + 4) = 3(7x + 4)

⇒ 20x + 16 = 21x + 12

⇒ 21x - 20x = 16 - 12

⇒ x = 4

Hari age = 5x = 5×4 = 20 years

Harry age = 7x = 7×4 = 28 years
