Simple Interest is the product of principal amount, rate of interest and the time duration (in years) by 100.
Example,
Input − p=5, r=4, t=5
Output − 1
Explanation: Simple Interest = (Principal Amount * Rate of Interest * Number of years) / 100
SI= 5*4*5/100 = 1
Example
#include<iostream>
#include <stdio.h>
using namespace std;
int main() {
//principle amount
float p = 5;
//time
float r = 4;
//rate in years
float t = 5;
// Simple interest
float SI = 0;
SI =(p * t * r) / 100;
printf("Simple Interest = %f ",SI);
return 0;
}Output
Simple Interest = 1.0000
