Answer:

1800 rupees

Explanation:

Given :

  • An electric refrigerator rated 500 watts operates for 6 hours a day

  • An air conditioner rated 1.5 Kw operates on 8 hours a day

  • 4 rupees per kwh Is the cost

To find :

  • Monthly bill of the house

Energy consumed by refrigerator = 500×6 = 3000 wh = 3 Kwh

Energy consumed by air conditioner = 1.5×8 = 12 Kwh

Daily consumption = 12+3 = 15 Kwh

Monthly consumption = 30×15 = 450 Kwh

Monthly bill = 4×450

Monthly bill = 1800 rupees

The cost of electricity bill is 1800 rupees
