The ages of Hari and Harry are in the ratio 5:7. Four years from now the ratio of their ages will be 3:4. Find their present ages.

Let the Ages of Hari and Harry be 5x years and 7x years.
According to question, 5x+4/7x+4 = 3/4
⟹ 4(5x+4) =3(7x+4)
⟹ 20x+16=21x+12
⟹ 20x-21x=12-16
⟹ -x=-4
⟹ x=4
Hence, the age of Hari = 5x = 5 x 4 = 20 years and the age of Harry = 7x = 7 x 4 = 28 years.
