Answer 2

Rahul age = 20

Haroon age = 28

Step-by-step explanation:

Let

present age of Rahul = 5x

Present age of haroon = 7x

After four years ,

Age of Rahul = 5x+4

Age of haroon = 7x+4

Present age =

$5x + 4 + 7x + 4 = 56$

$5x + 7x + 4 + 4 = 56$

$12x + 8 = 56$

$12x = 56 - 8$

$12x = 48$

$x = 4$

Then,

Rahul age = 5×4 = 20

Haroon age = 7×4 = 28
