Answer 1

Answer:

Explanation:

A month has approximately 30 days

So, according to the data present in the question,

The electricity consumption of one day is:

I) refrigerator= (400×10)=4000 W

ii) 2 fans=(2×80×12)=1920 W

iii)6 tubes= (6×18×6)=648 W

Total: (4000+1920+648)=6568W=6.568 KW=6.6 units

Electricity consumption of one month:

(6.6×30)=198 units

Total cost =198×3=594 rs.
