    Answer : Option A

    Explanation :

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

     

    Then,\( \frac { (6X+6)+4 } {(5X+6)+4 } \)=\( \frac { 11 } { 10 } \)

     

     10(6x + 10) = 11(5x + 10)

     

     5x = 10

     

     x = 2.

     

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