The difference between the ages of two sisters is the same as that of their father and mother. The elder sister is 24 years old. At the time of birth of the younger sister, their mother’s age was 30 years. If their father is 4 years elder to their mother, what was his age at the time of elder daughter's birth?

1. 35 years
2. 24 years
3. 30 years
4. 32 years

Answer 1

Correct Answer - Option 3 : 30 years

Let age of smaller sister = x years

Age of elder sister = 24 years

Mother's age at the time of birth of younger sister = 30 years

Father's age at the time of birth of younger sister = 34 years

According to ques;

Sister age Difference = Mother and father age Difference

24 - x = 4

x = 20 years

Father's age at the north of elder sister = 34 - 4 = 30 years

Hence, "30" is the correct answer.
