Answer 1

Answer:

Let Rahul's present age be y years.

Rahul's mother's present age=7y years

ATQ

7y=45

y=45÷7

:.y=6.428

Answer 2

Answer:

let rahuls age be y

mothers age will be 3y+7

rahuls mother is 45 years old ( given )

so

3y+7=45

3y=45-7

y=45-7/3

y=15-7(by simplification)

y=8

rahuls age is 8years
