Given: The simple interest incurred on a certain sum of money after 2.5 years at 3(1/4)% rate of interest per annum is 390.

To find: The value of the sum.

Solution:

  • Simple interest is calculated using the given formula,

        I = \frac{P * R * T}{100}

  • Here, I is the simple interest on the sum, P is thr principle amount or the sum, R is the rate of interest and T is the time period.
  • The rate of interest is given in the form of a mixed fraction, so it is to converted to improper fraction for further calculation,

        3\frac{1}{4} = \frac{13}{4}

  • On replacing the terms with the values given in the question,

        390 = \frac{P * 13 *2.5}{100 * 4}

        P = 4800

Therefore, the value of the sum is Rs. 4800.
