Answer:
The present ages of Rahul and Haroon are 20 and 28 respectively.
Step-by-step explanation:
Let Rahul's age = 5x
Let Haroon's age = 7x
A/Q (5x+4)+(7x+4) = 56
5x+7x+8 = 56
12x = 48
x = 4
Rahul's age = 5x = 5x4 = 20 years
Haroon's age = 7x = 7x4 = 28 years

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
⇒ 12x = 48
⇒ x = 48/12
⇒ x = 4
Therefore, Present age of Rahul = 5x = 5×4 = 20
And, present age of Haroon = 7x = 7×4 = 28
