The present age of mother is equal to the square of the age of her daughter after one year. If the age of daughter in 10 years hence will be 1 year less than the age of her mother in 10 years ago, find their present ages.

25 years

Step-by-step explanation:

m means mother's age

m = d^2

m + 5 = 3 (d + 5)

m + 5 = 3d + 15

m = 3d + 10

d^2 = 3d + 10

d^2 - 3d - 10 = 0

(d + 2) (d - 5) = 0

d + 2 = 0 OR d - 5 = 0

d = -2 or 5

m = d^2

m = (5) ^ 2

m = 25

The mother is 25 years old and the daughter is 5 years old!
