  • Question
  • How long will it take for a sum of money to grow from Rs.1250 to Rs.10,000, if it is invested at 12.5% p.a simple interest?


  • Options
  • A. 65years
  • B. 56years
  • C. 45years
  • D. 57years

  • Correct Answer
  • 56years 

    Explanation

    Simple interest is given by the formula SI = (pnr/100), where p is the principal, n is the numberof years for which it is invested, r is the rate of interest per annum

     

    In this case, Rs. 1250 has become Rs.10,000.

     

    Therefore, the interest earned = 10,000 ? 1250 = 8750.

     

    8750 = [(1250 x n x 12.5)/100]

     

    => n = 700 / 12.5 = 56 years.
