Program to find simple interest

21 Jun, 2022
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
 
The formula to calculate the simple interest is: simple_interest = (P * T * R) / 100 where P is the principal amount, T is time & R is the rate of interest.
