Answers
(10*420*30)÷100
1260 rs
Answer:
Rs. 1260 will be the cost of energy consumed by the heater in 30 days if it runs for 2 hours daily.
Explanation:
The heater has a power rating of 5 kW, which indicates that it uses 5 kW of energy per hour. That means the heater will use 10 kW/h of energy in two hours.
By multiplying 10 kilowatt-hours of energy by the price of one kilowatt-hour, which is 4.20 rupees, will give us the cost of the heater's energy consumption.
The daily energy bill will be 42 rupees for 10 kilowatt-hours multiplied by 4.20 rupees.
Multiplying the cost of energy used in one day by 30 days provides the total cost of energy used by the heater over those 30 days. Thus, he heater's 30-day energy bill will total Rs. 1260, or 42 times 30.
In conclusion, the heater's 30-day energy bill of Rs. 1260 will be incurred if it is operated for two hours daily.
