Secondly: three years ago and three years later, this year is the demarcation point.

Back to three years ago, the sum of their ages was: 54-6 (daughter) -6 (mother) =42 (year old).

Daughter's age: 1 times, mother's age: 5 times1+5 = 6,42 ÷ 6 = 7 (years old), that is, three years ago, daughter: 7 years old, mother: 5x7=35 (years old).

Three years later, this year's daughter: 7+3= 10 (years old), and mother: 35+3=38 (years old).

The final calculation: three years later, that is, three years later, the daughter: 10+3= 13 (years old) and the mother: 38+3=4 1 (years old) are exactly13+41=.

So the answer is that my mother is 38.
