Answer:

Rs. 720

Step-by-step explanation:

P = 500W = 0.5 kW

Energy consumed in a day = 0.5 x 12 = 6kWh

Energy consumed in 30 days = 6 x 30 = 180kWh

Total cost = 4 x 180 = Rs. 720

Step-by-step explanation:

1day = 500w×12h

24hrs = 6000wh.

2hr = 500wh » 1hr = 250wh =0 .25kwh

30days = (0.25)kwh ×30days ×₹4 (/kWh) ×24hr

= 6× 30 × 4

=₹ 720

this may be correct answer but not sure
