Answer 2

Answer:

it answer is 16500J

Explanation:

fen- 25W

used in- 10 hours

energy-power× time (1 case)

energy-25W× 10h

energy- 250J

tv-50W

used in-6hours (2 case)

energy-power×time

energy-50W×6h

energy-300J

now we added 1 case and 2 case- 250+ 300= 550

now energy consumption in one month

so,we multiply 550× 30= 16500J
