Answers
your question is un complete, kindley see to it
The total cost of running these equipment in september will be Rs 1620
Explanation:
One unit is equal to 1 kilowatt hour
1) capacity of electric heater = 1000w = 1 kilowatt
Time used = 5 hours
total kilowatt hour = 1 x 5 = 5Kwh = 5 units
cost of 1 unit = "Z" as you have not mentioned it in question
=> cost of 5 units = 5 xZ = 5Z Rs/ day
2) capacity of electric refrigerator = 400 w = 0.4 kilowatt
Time used = 10 hours
total kilowatt hour = 0.4 x 10 = 4 Kwh = 4 units
cost of 1 unit ="Z" as you have not mentioned it in question
=> cost of 4 units = 4 x Z =4Z Rs/day
Hence total cost per day = 4Z + 5Z =9Z Rs/day
Total cost in 1 months = 30 days x9ZRs/day = 270Z Rs ..... if month has 30 days
OR
Total cost in 1 months = 31days x9ZRs/day =279Z Rs ..... if month has 30 days
