Question

write a c program to input electricity unit charges and calculate the 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

Answer 1

include<stdio.h> 
main() 
{ 
int units; 
float at=0,sch=0,tx=0; 
printf("Enter number of units "); 
scanf("%d",&units); 
if(units<=50) 
at=units*0.50; 
else if(units>50 && units<=150) 
at=25+((units-50)*0.75); 
else if(units>150 && units<=250) 
at=75+((units-150)*1.20); 
else if(units>250) 
at=195+((units-250)*1.50); 
sch=(20*at)/100; 
tx=(10*at)/100; 

printf("------------------------------... 
printf("TOTAL Units %d\n ", units); 
printf("Unit charges %5.2f\n",at); 
printf("fuel surchage(20%) %5.2f\n",sch); 
printf("Govt. Tax (10%) %5.2f ",tx); 
printf("------------------------------... 
printf("Total Amount %5.2f",at+sch+tx); 
printf("------------------------------... 
} 

Answer 2

The first step is to set the equations for gravitational potential energy and work equal to each other and solve for force. W = PE is F × d = m × g × h, so F = (m × g × h) ÷ d. The second and final step is to plug the values from the problem into the equation for force.
