Q4.Annual demand for window frames is 10000. Each frame costs Rs. 200 and
ordering cost is Rs. 300 per order. Inventory holding cost is Rs. 40 per frame per
year. The supplier is willing to offer 2% discount if the order quantity is 1000 or
more, and 4% if order quantity is 2000 or more. If the total cost is to be
minimized, the retailer should
