AB Sdn. Bhd. (ABSB) is a manufacturer of superior basin, uses the First-In First-Out (FIFO) method in its process costing system. ABSB has produced the basin that passes through two sequential processing departments: Initial Department and Moulding Department. In the Moulding Department, all materials were added at the beginning of the process. Direct labor and manufacturing overhead were added uniformly. Percentage of completion in the Moulding Department for conversion costs is 40 percent for beginning work in process and 70 percent for ending work in process. Units and costs information related to the Moulding Department during October 2016 was summarized as follows: Units Costs Beginning work in process 1,800 Units started into production 48,750 Units started and completed 45,900 Units completed and transferred ? Ending work in process ? Beginning work in process: Transferred-in (RM) 88,100 Direct materials costs (RM) 74,400 Conversion costs (RM) 62,500 Total costs of beginning work in process (RM) 225,000 Current period costs: Transferred-in (RM) 238,875 Direct materials costs (RM) 136,500 Conversion costs (RM) 127,335 Total current period costs (RM) 502,710 REQUIRED:
(a)Prepare the following for the Moulding Department by using FIFO method:
i) Physical units from units to account for, units accounted for and equivalent units.
ii) Cost per equivalent unit.
ii) Cost accounted for.

(b)Assume the following scenario where all materials are fully added when percentage of completion for conversion cost reaches 50%. Calculate the following for the Moulding Department by using FIFO method:
i)Equivalent units.
ii) Cost per equivalent unit.
