Answer:
Electricity consumed = 20.4 kWh
Explanation:
Energy consumed by tube lights per day = 2x(40 x 8)
:::: = 640 W h
= 0.64 kWh
Energy consumed by fans per day = 2x (60 x 10)
=1200 W-h
= 1.2 kWh
Total energy consumed per day = 0.64 + 1.2 = 1.84 kWh
Total energy consumed per month =1.84 x 30 kWh
= 20.4 kWh
= 20.4 units.
