21

Transposing 4y to LHS and 12 to RHS

21

25

Dividing by 25 on both the sides

y=-20/25=-4/5

Let the common ratio between their ages be

According to the situation given in the question,

Multiplying both the sides by 4(7x+4)

4(5x+4)=3(7x+4)

20x+16=21x+12

Transposing 20x to RHS and 12 to LHS

4=x

x=4

Hari’s age = 5

Harry’s age = 7

Therefore, Hari’s age and Harry’s age are 20 years and 28 years respectively.
