Somebody Plz help me for the question below. A ltd.co uses a single raw material and converts that into a finished good.During the cureent period the cost of production and sale price were as follows: raw materials 3 units at rs.8 each=rs.24 cost of conversion =rs.26 total manufacturing cost=rs.50 selling price=rs.75 On the balance sheet date there is a steep fall in the price of the products to rs.45 because of competition and a fall in the material prices.Currently materials can be purchased and sales at rs.7 per unit.On the balance sheet date there are 100,000 units of raw material in stock purchased at a cost of rs.8 per unit.How can we value inventory of raw material as on balance sheet date as per International Accounting Standard-2
