and the age of harry be 7 y

four years hence ages are

5 y + 4 and 7 y + 4

5 y + 4 = 3

7 y + 4 = 4

the ages are 5 y + 4 x 4 = 20 y + 16

7 y + 4 x 3 = 21 y + 12

y = 4

hair's age is 20 yrs

harry's age is 21 yrs

then after four years from now the ratio of their ages will be 3:4

it seems that their present age of hari is 5*4=20.

and the age of harry is 7*4=28..... then their ratio 20/28=5:7.

then four years from now their age will be 3:4....,,, add 20+4=24

28+4 =32...

then the ages of them are 24 and 32 ..,,, it seems that 24/32 = 3:4...,,,
