Answer 2

Answer:

present age of mother =m, daughter=d

5 years hence; mother=m+5, daughter=d+5

It is given m+5=3(d+5)

m-3d=10 1st equation

5years ago: mother=m-5, daughter=d-5

It is given m-5=7(d-5)

m-7d=-30 2nd equation

subtract 1st equation from 2 nd equation

-7d+3d=-30-10=-40

4d=40, f=10

put this value of d in any of the above equations, you will get the value of m, m=40

daughter=10, mother=40
