Solution

#include<stdio.h>

int main()

{

  char s[1];

  int sum=0;

  int rpaper,rfee,arrear,afees;

  scanf("%s",s);

  scanf("%d",&rpaper);

  scanf("%d",&rfee);

  scanf("%d",&arrear);

  scanf("%d",&afees);

  sum=(rpaper*rfee)+(arrear*afees);

  switch(s[0])

  {

    case 'A':printf("The fee to be paid is Rs=%d",sum);

             break;

    case 'B':printf("The fee to be paid is Rs=%d",sum=sum+5000);

            break;

    case 'C':printf("The fee to be paid is Rs=%d",sum=sum+1500);

            break;

    case 'D': printf("The fee to be paid is Rs=%d",sum=sum+6500);
