Question

amans age is three times his sons age .ten years ago he was five times his sons age. find their present age.​

Answer 1

Step-by-step explanation:

let the present age of aman's be x

and the present age of aman's son be y

According to the question

x=3y (equation 1)

x-5=5(y-5) (equation 2)

Putting the equation first into equation second

3y-5=5y-25

3y-5y=-25+5

-2y=-20

y=-20/-2

y=10

x=3y

x=3×10

x=30

so,

the present age of aman is 30 years

and the present age of aman's is 10 years.

I hope it is useful for you.

please make me brainliest.

Thanks
