2. 1. Hira & Co. purchases electronic components from a supplier for Rs. 4 per unit. Their requirement is 3000 units during the coming year. It costs the company Rs. 20 to place an order and Rs. 1.25 per unit per year for carrying and storage. Compute the EOQ and, correspondingly, the number of orders per year and the total yearly costs associated with ordering, carrying and purchasing. II. In (i) above, the supplier offers a 2% discount for ordering quantities of 700 or more and 3% for or dering 1000 or more. Now, what is the most economic order quantity? III. Suppose that the actual cost of placing a purchase order is Rs. 50 and the inventory carrying cost is Rs. 0.5 per item per year. Unaware of these changes, the purchase department continues to place orders as derived from (i) above (ignore the information furnished in (ii) above for answering this portion).
