Question

Present age of Harry and Hari are in the ratio 5:7. Ten years from now their ages will be in the ratio of 7:9. Find their present ages

Answer 1

Step-by-step explanation:

Let the common ratio between their ages be x. Therefore, Hari's age and Harry's age will be 5x years and 7x years respectively and four years later, their ages will be (5x + 4) years and (7x + 4) years respectively. Therefore, Hari's age and Harry's age are 20 years and 28 years respectively.

Answer 2

Step-by-step explanation:

let hari present age be = 7x

harry = 5x

5x +10 / 7x+10 = 7/9

45x +90 =49x + 70

20 = 4x

x=5

harry= 5×5 = 25

.

hari =. 7×5 = 35
