                                     c.   Graphical method.

                                   Self Assessment

                                   State true or false:
                                   1.  The cost which is incurred to place an order is called as carrying cost.
                                   2.  Carrying cost is usually represented in terms of percentage on purchase price of average
                                       quantity to be held.
                                   3.  EOQ concept can be studied under two situations: in the absence of quantity discounts and
                                       in the presence of quantity discounts.

                                   13.1.2 In the Presence of Quantity Discounts

                                   Cost Comparison Method


                                   Under this method, generally the total cost of ordering two lots would be considered and the
                                   quantity discount to be availed and the lot which reveals the lowest total cost inclusive of the
                                   purchase price is said to be the EOQ.
