    Answer : Option B

    Explanation :

    S.I. on Rs. (260 - 20) for a given time = Rs. 20.

     

    S.I. on Rs. 240 for half the time = Rs. 10.

     

    T.D. on Rs. 250 = Rs. 10.

     

    S.I. on Rs. (260 - 20) for a given time = Rs. 20.

     

    S.I. on Rs. 240 for half the time = Rs. 10.

     

    T.D. on Rs. 250 = Rs. [\( \frac { 10 } { 2 50} \)x 260]
