This is a mathamatic problem so we will make 2 equations from the question. And by substuting in the equation we can solve it.Let us assume daughter age to be x years, and mother age to be m years.

Then m = 4x.

Substituing m with 4x, then 4x -x =27.

3x = 27.

x =9 age of the daughter.

Mother is 4 times the age of her daughter i.e 9 multiply by 4 =36.

Daughter age is 9 years and her mother is 36 years.
