Zeal Corporation is thinking about the dropping of its product Z. Sales of the product total Rs.400,000 per year; variable expenses total Rs. 270,000 per year. Fixed expenses charged to the product total Rs. 150,000 per year. The company estimates that Rs. 70,000 of these fixed expenses are not avoidable even if the product is dropped. If Product Z is dropped, what will be the net increase or decrease in profit of the company?
