The difference between simple interest on a certain sum at the annual rate of 8 percent for 5 years and 6 years is Rs. 26. What is the sum?

Rs. 325

If Principal = 100

Interest = Principal × Time

Simple interest at 8% for 5 years = 8 × 5

                                                 = 40%

Simple interest at 8% for 6 years = 8 × 6

                                                 = 48%

ATQ

48% - 40% = 26

8% = 26

1% = \(\frac{26}{8}\)

100% = \(\frac{26}{8}\) × 100

         = Rs 325
