Answer:
25 years.
Step-by-step explanation:
Given that a woman is 5 times as old as her daughter, while in 15 years time it will be two times as old as her daughter, to find a mother's presents age the following calculation must be performed:
5 x 5 = 25
25 + 15 = 40
40/2 = 20
5 + 15 = 20
Thus, the present age of the mother is 25 years, while that of her daughter is 5 years, with which the mother is five times the age of her daughter. In 15 years, the mother will be 40 and her daughter 20, with which she will only be twice her age.
