Question

the age of Hari and Harry are in the ratio 5 ratio 7 .four years from now the ratio of their ages will be the 3 ratio 4 find their present ages.

Answer 1

Given ages of Hari and Harry = 5:7

Let the ages of Hari and Harry be 5x and 7x years

4 year laters age of Hari = 5x + 4 years

4 year laters age of Harry = 7x + 4 years

Given that 4 years later rage of Hari and Harry = 3:4

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

⇒ 20x + 16 = 21x + 12

⇒ 21x – 20x = 16 – 12

∴ x = 4
