    B)  9 yrs

    C)  20 yrs           

    D)       None of these

    Correct Answer: B

    Solution :

     Let the ages of Kunal and Sanjay 6 years ago be 5x and 4x years respectively Then, \[\frac{(5x+5)}{(4x+5)}=\frac{10}{9}\] \[9(5x+5)=10(4x+5)\]  \[5x=5\]    \[x=1\] Sanjay's present age \[=(4x+5)=9\]years.
