  • Question
  • If the simple interest on a sum of money at 5% per annum for 3 years is Rs. 1200, find the compound interest on the same sum for the same period at the same rate.


  • Options
  • A. 1261
  • B. 1271
  • C. 1281
  • D. 1291

  • Correct Answer
  • 1261 

    Explanation

    Clearly, Rate = 5% p.a., Time = 3 years, S.I.= Rs. 1200. . .
    So principal=RS [100*1200]/3*5=RS 8000
    Amount = Rs. 8000 x [1 +5/100]^3 - = Rs. 9261.
    .. C.I. = Rs. (9261 - 8000) = Rs. 1261.
