Let the ages of Rahul and Haroon be 5x and 7x.

Four years later,

The ages of Rahul and Haroon will be (5x + 4) and (7x + 4) respectively.

According to the question,

(5x + 4) + (7x + 4) = 56

⇒ 5x + 4 + 7x + 4 = 56

⇒ 12x + 8 = 56

⇒ 12x = 56 - 8

\Rightarrow x=\frac{48}{12}

⇒ x = 4

∴, Present age of Rahul = 5x = 5×4 = 20

And, present age of Haroon = 7x = 7×4 = 28
