Let the present age of Rahul be 5x years.
Let the present age of Haroon be 7x years.

After 4 years,
Age of Rahul = (5x + 4) years
Age of Haroon = (7x + 4) years

The sum of their ages after 4 years is 56.

∴(5x + 4) + (7x + 4) = 56
∴5x + 4 + 7x + 4 = 56
∴12x + 8 = 56
∴12x = 56 - 8
∴12x = 48
∴x = 48/12
x = 4

∴Present age of Rahul = 5x = 5(4) = 20 years
Present age of Haroon = 7x = 7(4) = 28 years

Thus, the present age of Rahul is 20 years while the present age of Haroon is 28 years.
