Simple interest on a certain sum is one-fifth of the sum, and the rate of interest per cent per annum is 5 times the number of years. If the rate of interest increases by 3%, then what will be the simple interest (in ₹) on ₹5,600 for 6 years?
- ₹4668
- ₹4168
- ₹4268
- ₹4368
Correct answer: ₹4368
Solution
Use the relation SI = PRT/100 and the condition that SI is one-fifth of the sum. Also, the rate is 5 times the number of years, so the original rate can be determined from the given relation. After increasing the rate by 3%, compute SI on ₹5,600 for 6 years.
