4. (a) Minicomputer Company purchases a component for which it has a steady usage of 1,000
units per year. The ordering cost is Rs. 50 per order. The estimated cost of money invested in inventory is 25 per cent per year. The unit cost of the component is Rs 40. Calculate the optimal ordering policy and total cost of the inventory system, including purchase cost of the components.
