Question

A mother is twice as old as her son.if the 20 years ago the age of the mother was 10 times the age of the son.what is the present age of the mother

Answer 1

Let the son's age be x

The mother's age will be 2x

20 years ago

Son's age will be x-20

Mother's age=5x-20

According to the question

5x-20=10(x-20)

5x-20=10x-200

5x-10x= -200+20

-5x=-180

x= -180/-5

x=30

Mother's age=2*30=60
