Answer 2

Answer:

It is very easy dude.

Explanation:

Convert 100watt into kilowatt =0.1kw

Then, convert 60 watt into kilowatt =0.06 ×4 =0.24kw (because 4 bulbs of 60 watts)

Total kW =0.1 +0.24=0.34kw

Now total time,

5hour of 100watt bulb + 5 hour of 60 watt = 10 hour daily.

And for juanaury 31 days, then

31×10=310 hours.

Now electrical energy,

Electrical energy = power in kW × time in hours

Electrical energy = 0.34×31=10.54kwh

So, answer is 10.54kwh
