u2p4

An electricity board charges the following rates to domestic users to discharge large consumption of energy.

For the first 100 units – 60 P per unit

For next 200 units - 80P per unit

Beyond 300 units - 90 P per Unit

All users are charged a minimum of Rs.50.00. If the total amount is more than Rs. 300.00 then an additional surcharge of 15% is added. Write a program to read the names of users and number of units consumed and print out the charges with names.
