Question

How much should be paid for electricity consumption if the cost is Rs. 6.50 per unit, and the usage is 85 units, with the first 20 units charged at a different rate?

Answer 1

The cost of electricity consumption is Rs. 552.50, considering the different rates for the first 20 units and the remaining 65 units.

Step-by-step explanation:

To calculate the cost of electricity consumption, we need to consider the different rates for the first 20 units.

First, we calculate the cost for the first 20 units: Rs. 6.50 x 20 units = Rs. 130.

Then, we calculate the cost for the remaining 65 units: Rs. 6.50 x 65 units = Rs. 422.50.

Finally, we add the two costs together to get the total cost: Rs. 130 + Rs. 422.50 = Rs. 552.50.
