Answer 1

Explanation:

#include <stdio.h>

int main()

{

int unit;

float amt, total_amt, sur_charge;

/* Input unit consumed from user */

printf("Enter total units consumed: ");

scanf("%d", &unit);

/* Calculate electricity bill according to given conditions */

if(unit <= 50)

{

amt = unit * 0.50;

}

else if(unit <= 150)

{

amt = 25 + ((unit-50) * 0.75);

}

else if(unit <= 250)

{

amt = 100 + ((unit-150) * 1.20);

}

else

{

amt = 220 + ((unit-250) * 1.50);

}

/*

* Calculate total electricity bill

* after adding surcharge

*/

sur_charge = amt * 0.20;

total_amt = amt + sur_charge;

printf("Electricity Bill = Rs. %.2f", total_amt);

return 0;
