The age of a woman is 4 times the age of her daughter. 5 yrs hence,the age of the woman will be 3 times the age of her daughter.
poizon [28]

Answer:

10

Step-by-step explanation:

If W is the present age of the woman and D is the present age of the daughter, then:

W = 4D

W + 5 = 3(D + 5)

Substituting the first equation into the second:

4D + 5 = 3(D + 5)

4D + 5 = 3D + 15

D = 10

The daughter is 10 years old.
