  • Question
  • Father is aged three times more than his son Ronit. After 8 years, he would be two and a half times of Ronit's age. After further 8 years, how many times would he be of Ronit's age?


  • Options
  • A. 2 times
  • B.
    1 times
    2
  • C.
    3 times
    4
  • D. 3 times

  • Correct Answer
  • 2 times 

    Explanation
    Let Ronit's present age be x years. Then, father's present age =(x + 3x) years = 4x years.

    (4x + 8) = 5 (x + 8)
    2

    ⟹ 8x + 16 = 5x + 40

    ⟹ 3x = 24

    x = 8.

    Hence, required ratio = (4x + 16) = 48 = 2.
    (x + 16) 24
