Answer 1

Thanks for your question!! ✌

=============================

Solution,
========

Let comman factor be x

Present age of

Rahul = 5x

Rohit = 7x

After 4 years

Rahul = 5x + 4

Rohit = 7x + 4

Now,
A. to Q.

5x + 4 + 7x+ 4 = 56

=) 12x + 8 = 56

=) 12x = 48

=) x = 48/12

=) x = 4

===

Present ages of :

Rahul = 5 × 4 = 20

Rohit = 7 × 4 = 28
