Answer:
Energy consumed by 4 tubelights per day, E
tubelight
=(4)(40)(5)=800 WH
Energy consumed by 3 fans per day, E
fan
=(3)(80)(12)=2880 WH
Energy consumed by television per day, E
TV
=(100)(6)=600 WH
Total energy consumed per day, E=E
tubelight
+E
fan
+E
TV
∴ E=800+2880+600=4280 WH =4.280 KWH per day
Total energy consumed in 30 days, E
T
=30×4.280=128.4 KWH
Cost of electric energy =Rs. 3.00×128.4=Rs. 385.20
