Answer 1

Answer:

Powrr used in one hour,

Bulbs=5*80=400w

Fans2*100=200w

Motor=3kw=3000w

Geyser=5kw=5000w

1 unit=1000whr=1kwhr

Total power used in a hour=400+200+3000+5000

=8600 w

=8.6kwhr

Total energy consumed in day=8.6kw*8

=68.8kwhr

Energy cost per day=68.8*5

=344rs

Energy used in one month=68.8*30

=2064kwhr

Energy cost for 30 days=344*30

=10320rs
