Please help me I have to submit it tomorrow

Mr. Upreti has a metered tap using half-inch pipe in his house in Banepa. The meter reading of his house on 1 Baishakh was 1050 units and on 1 Jestha was 1075 units. According to NWSC, the minimum charge up to 10 units is Rs 110 and Rs 25 per unit for additional consumption of water, and 50% of the total charge is to be paid as sewerage service charge. Answer the following questions.
(I)How many litres of water is consumed in Baishakh month?
(ii) How much sewerage service charge should he pay?
(iii) Find the total bill including 50% sewerage service charge.
(iv) If he paid only Rs 465 for the consumption of water in Asar, how many units of water was consumed in the month of Asar?​

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.
