Given :  A mother said to her son, "15 years from now, you  will be as old as I was when you were 5years old  .

To Find :  What is the age of the  son & mother respectively?​

Solution:

Let say  Age of Son  =  S  years

Age of Mother  = M Years

15 years from now,   Son Age = S  + 15 Years

Son was 5 Years old  S - 5 Years before

Mother age S - 5 Years before   =  M - ( S - 5)

= M - S + 5

S  + 15 = M - S + 5

=> 2S  + 10  = M

present  age of the  son & mother are related by  2S  + 10  = M

Few Examples

Son    Mother    Verification

5          20          Son 5 mother 20 after 15 year Son will be 20

10         30          When son 5 mother 25 after  15 year Son will be 25

15         40          When son 5 mother 30 after  15 year Son will be 30
