Answer:
Let the current age of Rahul and Haroon be 5x and 7x respectively
Four years later their ages become 5x + 4 and 7x + 4 respectively.
According to the question,
5x + 4 +7x + 4 = 56
or 12x + 8 = 56
Transposing 8 to the RHS we get,
12x = 48
Dividing both sides by 12 gives,
x = 48/12 = 4
Thus current age of Rahul = 5*4 = 20
Haroon = 7*4 = 28
