The mother is 41 years old now, so 5 years ago she was 41-5=<<41-5=36>>36 years old
At that time the daughter's age was half hers so the daughter was 36/2=<<36/2=18>>18 years old
Now (5 years after that time) the daughter is 18+5=23 years old
In 3 years, the daughter will be 23+3=<<23+3=26>>26 years old
