24. Write a C program to input electricity unit charges and calculate total electricity bill according to the given condition: For first 50 units Rs. 0.50/unit For next 100 units Rs. 0.75/unit For next 100 units Rs. 1.20/unit For unit above 250 Rs. 1.50/unit An additional surcharge of 20% is added to the bill Solution :- #include<stdio.h> #include<conio.h> void main() { clrscr(); int unit; float amt,tot_amt,sur_charge; printf("Enter the Unit consumed :- "); scanf("%d",&unit); 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); } sur_charge = amt*0.20; tot_amt = amt+sur_charge; printf("The Total Bill is :- %f",tot_amt); getch(); } Output :-
