  • Question
  • The average age of a couple and their son was 40 years, the son got married and a child was born just two years after their marriage. When child turned to 10 years, then the average age of the family becomes 38 years. What was the age of the daughter in law at the time of marriage ?


  • Options
  • A. 12 years
  • B. 10 years
  • C. 14 years
  • D. 13 years

  • Correct Answer
  • 12 years 

    Explanation

    Given the average age of couple and their son = 40

    => Sum of age (H +W +S) = 40×3

    Let the age of daughter in law at the time of marriage = D years

    Now after 10 years,

    (H + S +W) + 3×12 + D +12 + 10 = 38×5

    178 + D = 190

    D = 190 -178 = 12 years
