<PRE><B>Question 800152</B>
The sum of the ages of a mother and a daughter is 50 years.
M + D = 50
M = 50 - D
Also 5 years ago the mother’s age was 7 times the age of the daughter. 
M - 5 = 7(D - 5)
Replace M with 50 - D
50 - D - 5 = 7D - 35
8D = 80
D = 10
Currently Daughter is 10 years old
Mother is 40 years old.
Hope this helps.
