Answer 1

Answer:

The age aman is 20and his father is 60

step by step explanation :

A man 's age is 3 times his son's age .

10yrs ago he was 5times his son's age.

By forming two equation and solving them both the ages ,

Let m = man's present age

and n = son's present age

A man's age is three times his son's age

m=3s

m-3s=0

10yrs ago he was 5times his son's age

m-10=5(s-10)

m-10=5s-50

m-5s =-50+10

m-5s=-40

-m+5s =40

+m-3s= 0

2s=40

s=40/2

m=3*20=60

so therefore son's age = s=40 and father's age= 60
