# Program to find simple interest

What is ‘Simple Interest’?
Simple interest is a quick method of calculating the interest charge on a loan. Simple interest is determined by multiplying the daily interest rate by the principal by the number of days that elapse between payments.
Simple Interest formula:

Simple interest formula is given by:
Simple Interest = (P x T x R)/100
Where,
P is the principle amount
T is the time and
R is the rate

Examples :

```EXAMPLE1:
Input : P = 10000
R = 5
T = 5
Output :2500
We need to find simple interest on
Rs. 10,000 at the rate of 5% for 5
units of time.

EXAMPLE2:
Input : P = 3000
R = 7
T = 1
Output :210
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

The formula to calculate the simple interest is: simple_interest = (P * T * R) / 100 where P is principal amount, T is time & R is rate of interest.
