Explanation:—
Let the age of Rahul be 5x and the age of Haroon be 7x, given that their ages are in the 5:7 ratio.
4 years later: the age of Rahul will be (5x + 4) and age of Haroon will be (7x + 4).
________________________________
| Present age. | After 4 yrs
Rahul | 5x | (5x + 4) ________________________________
Haroon | 7x | (7x + 4)
________________________________
The Sum of their ages after 4 years will be 56 years.
⇒ (5x+4) + (7x+4) = 56
⇒ 5x + 7x + 4 + 4 = 56
⇒ 12x + 8 = 56
⇒ 12x = 56 - 8
⇒ 12x = 48
⇒ x = 48/12 = 4
⇒ age of Rahul = 5x = 5(4) = 20 years
⇒ age of Haroon = 7x = 7(4) = 28 years
