Question 2 (25 marks) Seng Seng Limited uses a process costing system and the FIFO cost-flow assumption. Production begins in the crafting department where materials are added at the beginning of the process and conversion costs are incurred uniformly throughout the process. On 1 October, beginning work in process consisted of 20,000 units which were 70% complete and had a cost of $350,000, $100,000 of which were materials costs. During October, the following occurred: Materials added Conversion costs incurred Units completed and transferred out in October Units in ending work in process 31 October (30% complete) $450,000 $135,000 50,000 units 30,000 units (C) Determine the costs assigned to units completed and transferred out during October. (5 marks) (d) Controllable losses and non-controllable losses and gains may occur in manufacturing processes. Identify and define three possible and general types of process losses and gains. (3 marks) (e) Explain the need for equivalent units and why separate equivalent-unit totals are calculated for direct materials and conversion cost. (6 marks) If an examination of goods in production at the end of the period revealed 30,000 units that are, on average, 70% complete, would it be correct to say that 21,000 units were finished during the period?
