#include<stdio.h>

int main()
{
   float amount, rate, time, si;

   printf("\nEnter Principal Amount : ");
   scanf("%f", &amount);

   printf("\nEnter Rate of Interest : ");
   scanf("%f", &rate);

   printf("\nEnter Period of Time   : ");
   scanf("%f", &time);

   si = (amount * rate * time) / 100;
   printf("\nSimple Interest : %f", si);

   return(0);
}

Output:

Enter Principal Amount : 5669.56

Enter Rate of Interest : 5.6

Enter Period of Time   : 3.0

Simple Interest : 952.486084
