(12 marks) (b) Calculate and discuss the effect that each of the three methods of inventory pricing will have on the reported profit for the first week's trading. (8 marks) (c) Both UK and International Accounting Standards state that LIFO is not an acceptable method of inventory valuation for external reporting.
