Explanation:

#include <stdio.h>

int main()

{

int calls;

float bill;

printf("Enter number of calls :");

scanf("%d", &calls);

if (calls <= 100)

{

bill = 200;

}

else if (calls > 100 && calls <= 150)

{

calls = calls - 100;

bill = 200+(0.60 *calls);

}

else if (calls > 150 && calls <= 200)

{

calls = calls - 150;

bill = 200+(0.60 *50) + (0.50 *calls);

}

else

{

calls = calls - 200;

bill = 200 + (0.60 * 50) + (0.50 * 50) + (0.40 * calls);

}

printf("Your bill is Rs. %0.2f", bill);

return 0;
