If the cost of 1 unit is Rs. 4.50/-, find the amount to be paid for the electricity bill for December 2021​

Answer 1

The Appropriate List of the Electrical gadgets consumption in the month of December 2021 is given in the File Attached.

Firstly, We should convert this Power [watt] into Kilowatt and after that multiply the time, by how much it used.

• LED Bulbs - 0.32 kWh
• TV (Plasma) - 1.5 kWh
• Geysar - 6 kWh
• Convector - 7.5 kWh
• Charging Mobile - 0.024 kWh
• Laptop Charging - 0.12 kWh

Now, we also know that there are 31 days in the month of December. so we gonna multiply the Total Electrical Energy consumed with 31.

→ Total Energy [15.464 kWh] × 31

→ 479.384 kWh

Finally, We know that cost of Electricity at the rate of ₹4.5 per unit.

→ 479.384 × 4.5

→ ₹ 2157.228
