Question

The sum of the ages of 4 members of a family 6 years ago was 110 years. Today, when the daughter has been married off and replaced by a daughter-in-law the sum of their ages is 115. Assuming that there has been no other change in the family structure and all the people are alive, what is the difference in the ages of the daughter and the daughter-in-law? (IBPS PO)

• A.
  22 years
• B.
  11 years
• C.
  25 years
• D.
  19 years
• E.
  15 years

Answer 1

The correct option is D

19 years
Sum of the ages six years ago = 110
Sum of their ages now = 110 + 24 = 134
Sum of their ages after their ages after the daughter is left and replaced by daughter-in-law = 115
Difference = 134 – 115 = 19 years
