Question 3

Assuming the electric consumption per day to be 12 kWh and the rate of electricity to be Rs 6.25 per unit, find how much money is to be paid in a month of 30 days?

Answer

Electric energy consumed per day = 12 kWh
Electric energy consumed for 30 days = 12 x 30 = 360 kWh

1 kWh = 1 unit
360 kWh = 360 units
1 unit cost = Rs 6.25
360 units cost = 360 x 6.25 = Rs 2250

So money to be paid for 30 days = Rs 2250.
