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 present ages of Hari and Harry are 5x and 7x

Then, four years later, Hari age will be 5x+4 years and Harry age will be 7x + 4 years


Now,



Thus, presently, Hari age is 20 and Harry age is 28
