/*c program for calculate simple interest*/

#include<stdio.h>

#include<conio.h>

int main()

{

 float p,rate,time,si;

 printf("Enter principal amount : ");

 scanf("%f", &p);

 printf("Enter rate of interest : ");

 scanf("%f", &rate);

 printf("Enter time period in  year : ");

 scanf("%f", &time);

/*calculating simple interest*/

 si=(p*time*rate)/100;

 printf("\nSimple Interest = %2f",si);
