    Answer : Option B

    Explanation :

     S.I. on Rs. 750 = T.D. on Rs. 960.

     

     This means P.W. of Rs. 960 due 2 years hence is Rs. 750.

     

     T.D. = Rs. (960 - 750) = Rs. 210.

     

    Thus, S.I. on R.s 750 for 2 years is Rs. 210. r       

     

    Rate=\([ \frac { 100*210 } { 750*2} ]\)%=14%
