The cost of the energy consumed in the month is 15000w 300 hours.

Answer 2

Hey..Here is your answer u r looking for...

Power of Refrigerator = 500w =>500/1000=>0.5kw

time = 10hour /day
time in one month = 10*30 =>300hour

Now,
power = energy consume/time taken
0.5 = E.C /300
E.C = 300*0.5=>150kw-h

Energy consume by refrigerator in a month = 150kw-h..

Note:- rate of per kw-h is not given so,we can not find cost of energy...
