  • Question
  • The interest on Rs.750 for 2yrs is the same as the True Discount on Rs.960 due 2yrs hence . If the rate of interest is same in both cases,it is:


  • Options
  • A. 12%
  • B. 14%
  • C. 15%
  • D. 16

  • Correct Answer
  • 14% 

    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 

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

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

    Rate =[ (100 x 210) / (750 x 2) ] % = 14%
