Answer 1

Answer:

As per given energy consumed per day in kWh units is:

E₁= 60 x 15/ 1000

=900/1000

=0.9 kWh

E₂= 750 x 10/ 1000

=7500/1000

=7.5kWh

so, total energy consumed per day= E₁ + E₂= 0.9 + 7.5 = 8.4 kWh

Total energy consumed during a month of 30 days = 30 x 8.4= 252 units.

So, electicity bill @ ₹2 = ₹2 x 252= 504 units.
