  • Question
  • Six years ago, the ratio of the ages of Kunal and Sagar was 6 : 5. Four years hence, the ratio of their ages will be 11 : 10. What is Sagar's age at present?


  • Options
  • A. 16 years
  • B. 18 years
  • C. 20 years
  • D. Cannot be determined
  • E. None of these

  • Correct Answer
  • 16 years 

    Explanation
    Let the ages of Kunal and Sagar 6 years ago be 6x and 5x years respectively.

    Then, (6x + 6) + 4 = 11
    (5x + 6) + 4 10

    ⟹ 10(6x + 10) = 11(5x + 10)

    ⟹ 5x = 10

    x = 2.

    ∴ Sagar's present age = (5x + 6) = 16 years.
