A woman is 4 times as old as her daughter. In 12 years time, the sum of their ages will be 89. How old was the woman when her daughter was born?
Let the daughter's age =D
Her mother's age =4D
D+12+4D+12 =89
5D =89 - 24
5D =65
D = 65/5
D=13 years - daughter's age now
13 x 4 =52 mother's age now.
52 - 13 =39 years - mother's age when her daughter was born.
