Answer 2

Ram = 20 , Mohan = 28

Step-by-step explanation:

Let ,

Ram Present age = 5x

Mohan present age = 7x

Four years later ,

Ram age = (5x+4) years

Mohan age = (7x+4) years

Let ,

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

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

$12x + 8 = 56$

$12x = 56 - 8$

$12x = 48$

$x = 4$

Ram age = 5×4 =20

Mohan age = 7×4 = 28
