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.
