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 at 5 per unit for next 150 units at 10 per unit more than 250 units at 20 per unit Also add meter charges of 75 per month to calculate the total water bill.

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 .

Algorithm to Calculate Total Water Bill Charges

1. INPUT: Number of units consumed

2. PROCESS:

   • If units <= 100:

     • Total charges = units * 5

   • Else if 100 < units <= 250:

     • Total charges = (100 * 5) + ((units - 100) * 10)

   • Else:

     • Total charges = (100 * 5) + (150 * 10) + ((units - 250) * 20)

   • Add meter charges of 75

3. OUTPUT: Total water bill charges

Pseudocode

INPUT units
SET totalCharges = 0
IF units <= 100 THEN
    totalCharges = units * 5
ELSE IF units <= 250 THEN
    totalCharges = (100 * 5) + ((units - 100) * 10)
ELSE
    totalCharges = (100 * 5) + (150 * 10) + ((units - 250) * 20)
END IF
totalCharges = totalCharges + 75
PRINT totalCharges

Explanation

1. Input: Accept the number of units consumed by the customer.

2. Process:

   • For the first 100 units: The charge is 5 per unit, so multiply units by 5.

   • For next 150 units: If units are more than 100 but less than or equal to 250, calculate the charge for the first 100 units and add the charge for the remaining units at 10 per unit.

   • For units beyond 250: Calculate the charge for the first 100 units, the next 150 units, and add the charge for the remaining units at 20 per unit.

   • Add meter charges: A fixed meter charge of 75 per month is added to the total charges.

3. Output: Print the total water bill charges.
