Question

The age of the mother was 30 years at the time of the birth of her daughter. After 5 years, the mother's age will be 7 times the age of the daughter at that time. After twenty years, what will be the ratio of their ages​

Answer 1

From equation (1)&(2), we have

50−y−2y=20

3y=30

⇒y=10

Substituting the value of y in equation (1), we get

x=50−10=40
