Answer 1

Answer:

present age of Rahul is 20 and of Arun is 28

Answer 2

Answer:

let the common ratio be x

so Rahul's age =5x

and Arun's age= 7x

Four years later,

Rahul age=5x+4

Arun age=7x+4

According to question

5x+4+7x+4=56

12x+8=56

12x=56-8

12x=48

x=48/12

x=4

Now,Arun age =7x

=7(4)

=28

Rahul age=5x

=5(4)

=20
