Q12) A telephone company charges for using telephone from their consumers according to the calls made (per month) as per the given tariff:

 Numbers of calls Charge Up to 50 calls No charge (free) For next 100 calls exceeding 50 call Rs. 2 per call For next 200 calls exceeding 150 call Rs. 1.50 per call + Previous 100 calls bill amount More than 350 calls Rs. 1 per call + Previous 200 calls bill amount + previous 100 calls bill amount

However, monthly rental charge is Rs.180/- per month for all the consumers for using Telephones. Write a program in Python to calculate and display the monthly telephone bill along with total numbers of calls and monthly rental.

#### Program

mr=180
call=int(input('Enter total number of calls '))

if call<=50:
bill=0
elif call>50 and call<=150:
bill=(call-50)*2
elif call>150 and call<=350:
bill=(call-150)*1.5+(100*2)
else:
bill=(call-350)*1+(200*1.5)+(100*2)

print('Total Calls = {}'.format(call))
print('Total Calls Charges = {:.2f}'.format(bill))
print('Fixed Monthly Rental = {}'.format(mr))
print('Total Bill Amount = {:.2f}'.format(bill+mr))

#### Output

Enter total number of calls 243
Total Calls = 243
Total Calls Charges = 339.50
Fixed Monthly Rental = 180
Total Bill Amount = 519.50
