Write an algorithm to display the total water bill charges of the month depending upon the number of units consumed

Q. 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:-

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
