sum of the present ages of mother and her daughter is 50 years. After 20 years,mother's age will be twice her daughter's age at that time. Find their present ages

Answer»

Let daughter present age = xThen mother present age = 50 - x

After 20 yearsMother age = (50-x) + 20Daughter age = x + 20

As per given condition70 - x = 2(x + 20)70 = 2x + x + 403x = 30x = 30/3 = 10

Therefore,Daughter present age = x = 10 yearsMother present age = 50 - x = 50 - 10 = 40 years
