Question

C#

3. Write a program to calculate and print the Electricity bill of a given customer. Read the units consumed by the user from the keyboard and display the total amount to pay as per the table below. (Total Amount to pay = Units * Charge) [20 marks] Units <=200 201-400 401-600 601-800 >800 Charge/Unit 1.5 1.8 2.1 2.5 2.7 Sample I/O Enter the unit consumed by the customer : 300 Total Amount to pay 540
