Problem # 5: 

From the figures given below, calculate Economic Order Quantity (EOQ) and Total cost at EOQ?

Total consumption of material per year         10,000 kgs                Buying cost per order Rs. 50

Unit cost of material                                        Rs. 2 per kg            Carrying and storage cost 8%


economic order quantity

EOQ = 2,500 Units


Total Inventory Cost = [Fixed ordering cost (F) * Number of Order per year N] + [Carrying Cost (C)* EOQ/2]

Total Inventory Cost = [50 * 10,000/2,500] + [(2*0.08)* 2,500/2]

Total Inventory Cost = 200 + 200

Total Inventory Cost = Rs.  400
