  • Question
  • Karthik is now 32 years old and his son is 7 years old. In how many years will Karthik be twice as old as the son?


  • Options
  • A. 18
  • B. 25
  • C. 7
  • D. 15

  • Correct Answer
  • 18 

    Explanation

    Given Karthik?s age = 32 years

    Karthik?s son age = 7 years

    Difference between their ages = K - S = 32 - 7 = 25 years ?.(1)

    Now, required K = 2S ??(2)

    Put (2) in (1)

    2S - S = 25

    => S = 25 years

    Hence, at the age of 25 years of Karthik?s son, Karthik will be twice as his son?s age.

    25 - 7 = 18 years

     

    Therefore, after 18 years the father be twice as old as the son.
