Write a Python 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 :- 

# Static

unit = 150
if unit<=50:
amt = unit *0.50
elif unit <=150:
amt = 25+((unit – 50)*0.75)
elif unit<=250:
amt = 100 +((unit-50)*1.20)
else:
amt = 220+((unit-250)*1.50)
sur_charge = amt * 0.20
tot_amt = amt + sur_charge
print(“The total amt is :- “,tot_amt)

#Dynamic

unit = int(input(“Enter the amount :- “))
if unit<=50:
amt = unit *0.50
elif unit <=150:
amt = 25+((unit – 50)*0.75)
elif unit<=250:
amt = 100 +((unit-50)*1.20)
else:
amt = 220+((unit-250)*1.50)
sur_charge = amt * 0.20
tot_amt = amt + sur_charge
print(“The total amt is :- “,tot_amt)

Output :-
