Hint:Use the formula of Power, P = VI

Step 1: Note the given values

Potential difference, V=250V

Current, I =8A

Step 2: Finding the power consumed by Bulb

Power, P= VI

Putting the values in formula:

P=250×8

P=2000watts

Bulb works on the average of 8 hours a day.

So, Power consumed in one day:

P=2000×8

P=16000Wh = 16000kWh

Hence, Power Consumed in one day is 16kWh

Step 2: Finding the monthly bill electricity.

We know that:

Power Consumed in one day is 16kWh

Power Consumed in 60 days = 60×16 kWh = 960kWh

As given,

Bill for 6kWh = Rs. 5

So, Bill for 960kWh =

×960

= Rs. 800.

So, Bill for 1 month =

800

= Rs. 400

Hence, monthly bill for electricity is Rs. 400.
