   float p, r, si;  //Declaring Variable.
   int t;  //Declaring Variable.

   printf("Enter the values of p,r and t\n");   //For printing
   scanf ("%f %f %d", &p, &r, &t);   //For Input.

     si = (p * r * t)/ 100.0;  //Calculation
   
   printf ("Rate   = Rs. %5.2f%\n", r); //For printing
   printf ("Time   = %d years\n", t);  //For printing
   printf ("Simple interest  = %5.2f\n", si); //For printing
     getch();   //Getting a chracter or waiting for key press.
  return 0;

}
