Mohawk Machining, which uses a process-costing system, adds material at the beginning of production and incurs conversion cost evenly throughout manufacturing. The following selected information was taken from the company's accounting records: Total equivalent units of materials: 8,000 Total equivalent units of conversion: 7,400 Units started and completed during the period: 6,500 On the basis of this information, the ending work-in-process inventory's stage of completion is:. A- 80%.
B- 70%.
C- 60%. - 40%.
D- some other percentage not listed above.

C. 60%

Explanation:

Equivalent unit of Materials = 8,000.00      

Equivalent unit of Conversion = 7,400.00      

Units started and completed = 6,500.00

Since Materials are entered in the beginning it means that out of 8000 Units of Materials 6500 units are in Units started and completed and remaining 1500 Units are in Closing inventory. It also means that 1500 units are in Closing Inventory of Conversion and Equivalent production of conversion part of 1500 Units are 900 Units (7400-6500).

Let % Completion be x      

X% of 1500 = 900      

X = 900*100/1500      

X = 60%.
