Introduction

Simple interest is a type of interest calculated on the initial principal amount, and it is not compounded over time. In this article, we will discuss how to calculate simple interest and the amount after a certain period of time. We will use a real-life example to illustrate the concept.

What is Simple Interest?

Simple interest is calculated using the formula:

Simple Interest (SI) = (Principal (P) x Rate (R) x Time (T)) / 100

Where:

  • Principal (P) is the initial amount of money borrowed or invested.
  • Rate (R) is the interest rate per annum.
  • Time (T) is the time period in years.

Calculating Simple Interest

Let's consider an example to calculate simple interest. Suppose we have a sum of rupees that we want to invest for 12 years at the rate of 5% per annum. We need to find the simple interest and the amount after 12 years.

Given Values:

  • Principal (P) = 100 rupees
  • Rate (R) = 5% per annum
  • Time (T) = 12 years

Calculating Simple Interest:

Using the formula for simple interest, we can calculate the simple interest as follows:

Simple Interest (SI) = (100 x 5 x 12) / 100 Simple Interest (SI) = 600 rupees

Calculating Amount:

To find the amount after 12 years, we need to add the simple interest to the principal amount.

Amount = Principal + Simple Interest Amount = 100 + 600 Amount = 700 rupees

Conclusion

In this article, we discussed how to calculate simple interest and the amount after a certain period of time. We used a real-life example to illustrate the concept and calculated the simple interest and amount using the formula. We hope this article has provided you with a clear understanding of simple interest and amount calculation.
