Question

Write an algorithm to display the total water bill charges of the month depending upon the number of units consumed by the customer as per the following criteria:

• for the first 100 units @ 5 per unit
• for next 150 units @ 10 per unit
• more than 250 units @ 20 per unit

Also, add meter charges of 75 per month to calculate the total water bill.

Answer 1

Input unit

If unit <= 100 then
    Bill = unit * 5

Elif unit <= 150 then
     Bill = unit * 10

Elif unit <= 250 then
     Bill = unit * 20

Calculate total bill = bill + 75
Print total bill
