[8 marks]For a special component outsourced to a vendor and used in textile machinery manufactured by Amar Machine tool works, we have the following situation: Yearly Demand: 3,00,000 units Purchase Quantity: 1,00,000 units Safety Stock: 50,000 units The ordering cost, independent of purchase quantity, is Rs 1500 each purchase. The price of the component is Rs 75/unit. Annual holding cost is 20% of the value of the component (inventory interest rate 20%). Assuming 230 working days per year. Calculate (I) Average Inventory Level ( Including Safety Stock) (II) Total inventory costs per year and total inventory costs per working day with purchase quantity 1,00,000 units
