You recently bought an electric kettle for your kitchen, and you want to estimate how much it costs to run every month. The kettle operates at 230V and consumes 2000W (or 2kW) when in use. You typically use it for 30 minutes per day.

Electricity companies charge based on energy consumption in kilowatt-hours (kWh). The energy consumption is calculated as:

E=P × t

Where:

• E is the energy consumed in kilowatt-hours (kWh)
• P is the power in kilowatts (kW)
• t is the usage time in hours

The monthly electricity cost is then calculated as:

Cost=E × Rate

Where:

• Rate is tthe cost per kWh in Indian Rupees (INR).

Write a function that takes power rating (W), daily usage time (minutes), and electricity rate (cost per kWh in INR) and returns the estimated monthly cost of running the appliance.
