# Simple Interest Questions for Competitive Exams

Vikram Singh4 years ago 9.3K Views

Simple interest is the most important part of the mathematics subject and often questions are asked in all competitive examinations. When a person borrows money from another person or from a bank, they have to pay interest at a fixed rate from time to time. But, when interest is charged only on the principal, at the same rate for a fixed period of time, then it is called simple interest. Also, interest can be seen as "rent of money". Simple interest is derived with the help of a formula such as simple interest = principal × time × rate / 100 or simple interest = compounding - principal.

Here today in this article, we have covered simple interest-based questions to help the aspirants, which will help you to solve stressful questions in the exam and build a strong foundation. Also, if you practice these questions regularly, then you can get full marks under this topic.
