A particular household utilizes three electrical appliances for six hours daily if the appliances are rated 80W, 100W, and 120W respectively. Calculate the electrical bills paid monthly if an average month is 31 days. [1kwh = #24.08k]
- ₦ 2843.22k
- ₦ 1950.22k
-
₦ 1343.66k
- ₦ 46.23k
The correct answer is: C
Explanation
Total power consumption = 80 + 100 + 120 = 300W
P in KW = 0.3KW
Energy consumed = 0.3 x 6 = 1.8KWh
Monthly energy consumption = 1.8 x 31 = 55.8KWh
Cost of Monthly energy usage = 55.8 x 24.08 = #1343.664k ( since 1kwh = #24.08k)
