As we have studied that electricity is produced in power stations and supplied to our homes through transmission lines. During transmission, some part of electricity is lost due to heating effct produced by transmission lines. If the power station produces of electricity and the distance between power station and the city is and the rate of loss is , find out the total electricity that reaches the city and also the electricity lost due to heating effect in megawatts. If the cost of electricity is per megawatt, then calculate the loss in rupees also.
