present ages ratio = 5:7
let the common factor be x
therefore their ages are 5x and 7x
after 3 years ratio=3:4
after 3 years their ages 5x+3 and 7x+3
so. 5x+3:7x+3=3:4
cross multiplying we get:
4(5x+3)=3(7x+3)
20x + 12= 21x + 9
21x - 20x=12-9
x=3
present age of hare is 5x = 15
present age of harry is 7x = 21
