How to calculate simple interest?

Simple interest can be calculated using the formula: Simple Interest SI=(p*t*r)/100.

Here p is the principal amount. For this amount we are calculating the interest. t is the timeperiod and r is the interest rate.

Take input of p,t and r then multiply them and after that divide them by 100 and which results in rate of interest.


c program to find simple interest

#include<stdio.h>
int main(int argc, char const *argv[])
{
	int p,t,r;
	printf("\n\n\tEnter principal, time and rate of interest:\n\t");
	scanf("%d%d%d",&p,&t,&r);
	float interest=(p*t*r)/100;
	printf("\n\tInterest amount is %f\n\n",interest);
	return 0;
}

Output:

	Enter principal, time and rate of interest:
	1000 1 25

	Interest amount is 250.000000
