6.A company manufactures two main products, J and K, and the by-product L. The by-product has a net realisable value of $2 per litre. The following information relates to last month, when there were no opening inventories.
Joint costs last month were $290,000. Company policy is to apportion joint costs on a physical measure basis and to treat the net realisable value of the by-product as a deduction from the cost of the main products.What was the cost value of last month's closing inventory of product J?
A.$13, 500
B.$15,000
C.$16,200
D.$16,400
答案：$15,000
Net realisable value of by-product L = $20,000 (10,000 X $2)
Joint costs of products J and K = $270,000 (290,000 - 20,000)
Costs allocated to product J = $150,000 (270,000 x (50,000/ (50,000 +40,000)))
Production of J = 50,000 litres
Costs allocated toJ = $150,000 = $3 per litre ($150,000 / 50,000)
Cost value in product J inventory at the end of the month = $ 15,000 ($3 x5,000)
