Answer 1

Answer:

(C) 40 years

Step-by-step explanation:

Let mother be 'M' and Daughter be 'D'

Given,

The sum of the ages of a mother and her daughter is 50 years.

M+D=50                   ------------(1)

Also 5 years ago, the mother's age was 7 times the age of the daughter.

here the question must be the mother's age is 7 times the age of the daughter at that time

mother's age and her daughter's age 5 years ago

M-7 and D-7

M-5=7(D-5)

M-7D=-30                --------------(2)

by solving (1) and (2)

we get Daughter is 10 years and Mother is 40 years old
