A 2-kW electricity heater is used 2.5 hours per day. If electricity costs 5 Rs/kWh then its monthly cost will be Rs. 750.

### A 2-kW electricity heater is used 2.5 hours per day. If electricity costs 5 Rs/kWh then its monthly cost will be

Total bill = power in kilowatt * time in hours * No. of days * electricity cost per kWh

## Given Date:

1. Power p = 2 kW
2. Time t = 2.5 hours
3. No. of days = 30
4. Electricity cost per kWh = Rs. 5

## Solution:

Total Bill = 2*2.5*30*5 = Rs. 750
