  • Question
  • A certain sum is invested at simple interest at 18% p.a. for two years instead of investing at 12% p.a. for the same time period. Therefore the interest received is more by Rs. 840. Find the sum ?


  • Options
  • A. Rs. 5858
  • B. Rs. 8800
  • C. Rs. 7000
  • D. Rs. 6350

  • Correct Answer
  • Rs. 7000 

    Explanation

    Let the sum be Rs. S.
    (S x 18 x 2)/100 - (S x 12 x 2)/100 = 840 => 36S/100 - 24S/100 = 840

    => 12S/100 = 840 => S = 7000.
