CPL 5 - ELECTRICITY BOARD CHARGES

5. An electricity board charges the following rates for the use of electricity: for the first 200 units 80 paise per unit: for the next 100 units 90 paise per unit: beyond 300 units Rs 1 per unit. All users are charged a minimum of Rs. 100 as meter charge. If the total amount is more than Rs 400, then an additional surcharge of 15% of the total amount is charged. Write a program to read the name of the user, a number of units consumed and print out the charges.

ALGORITHM:

Step 1: start
Step 2: read customer number
Step 3: read customer name
Step 4: read unit consumed
Step 5: unit is less than 200, charge 0.80 per unit
Step 6: if the unit is greater then 200 and less then 300, charge 0.90 per unit
Step 7: unit is greater than 400 charges 1.00 per unit,
Step 8: calculate the amount by unit* charge
Step 9: if the amount is greater then 400, then an additional surcharge of 15% of the total amount is charge total-amount=amt+surcharge.
Step 10: Addition of rs 100 as a minimum meter charge for all customer to the total amount.
Step 11: print customer number,name,unit_consumed_amount,surcharge,totalAMOUNT+100

Step 12:stop
