Answer:
To solve the given questions, we need to calculate the water consumption, sewerage service charge, and the total bill for Mr. Upreti. Let's break down each question:
(i) How many liters of water were consumed in Baishakh month?
To determine the water consumption, we need to find the difference between the meter readings on 1 Jestha and 1 Baishakh. Each unit of water corresponds to one cubic foot, which is approximately equal to 28.3168 liters.
Water consumption = (1075 units - 1050 units) * 28.3168 liters/unit
Water consumption = 25 units * 28.3168 liters/unit
Water consumption = 707.92 liters
(ii) How much sewerage service charge should he pay?
The sewerage service charge is 50% of the total charge. First, we need to calculate the total charge for water consumption. The minimum charge is Rs 110 for up to 10 units, and for additional consumption, it is Rs 25 per unit.
Total charge for water consumption = Rs 110 + (additional units * Rs 25)
additional units = Total units consumed - 10 units (since up to 10 units have a fixed charge)
additional units = 25 units - 10 units
additional units = 15 units
Total charge for water consumption = Rs 110 + (15 units * Rs 25)
Total charge for water consumption = Rs 110 + Rs 375
Total charge for water consumption = Rs 485
Now, we can calculate the sewerage service charge:
Sewerage service charge = 50% of total charge for water consumption
Sewerage service charge = 0.5 * Rs 485
Sewerage service charge = Rs 242.50
(iii) Find the total bill including 50% sewerage service charge.
The total bill includes the charge for water consumption and the sewerage service charge.
Total bill = Total charge for water consumption + Sewerage service charge
Total bill = Rs 485 + Rs 242.50
Total bill = Rs 727.50
(iv) If he paid only Rs 465 for the consumption of water in Asar, how many units of water were consumed in the month of Asar?
We can calculate the units of water consumed by rearranging the equation for the total charge for water consumption:
Total charge for water consumption = Rs 110 + (additional units * Rs 25)
Rs 465 = Rs 110 + (additional units * Rs 25)
Rs 355 = additional units * Rs 25
additional units = Rs 355 / Rs 25
additional units = 14.2 units
Total units consumed = 10 units (minimum charge) + additional units
Total units consumed = 10 units + 14.2 units
Total units consumed = 24.2 units
Therefore, in the month of Asar, Mr. Upreti consumed approximately 24.2 units of water.
