If the electric consumption of your house is 20 kWh in one day and the cost of electricity is Rs 4 per unit, find out how much electricity bill you will have to pay for one month(30 days).
Rs.2400
1 kWh is the 1 unit of electrical energy consumed.
Given:
Units consumed in 1 day = 20 kWh = 20 units
∴ Units consumed in one month = 30×20 units=600 units
Cost per unit = Rs.4
∴Cost for 600 units =
600 units×Rs.41unit=Rs.2400
Hence, electricity bill for 1 month is Rs.2400
