Department G had 3,600 units 25% completed at the beginning of
the period, 11,000 units were completed during the period, 3,000
units were 20% completed at the end of the period, and the
following manufacturing costs were debited to the departmental work
in process account during the period:
| Work in process, beginning of period | $40,000 | 
| Costs added during period: | |
| Direct materials (10,400 units at $8) | 83,200 | 
| Direct labor | 63,000 | 
| Factory overhead | 25,000 | 
All direct materials are placed in process at the beginning of
production, and the first-in, first-out method of inventory costing
is used. What is the total cost of the units started and completed
during the period (round unit cost calculations to whole
dollars)?
a.$211,200
b.$190,275
c.$20,934
d.$120,060
Solution:
| Department G | |||
| Computation of Equivalent unit (FIFO) | |||
| Particulars | Physical units | Material | Conversion | 
| Units to be accounted for: | |||
| Beginning WIP Inventory | 3600 | ||
| Units started this period | 10400 | ||
| Total unit to be accounted for | 14000 | ||
| Units Accounted for: | |||
| Units completed and transferred out | |||
| From
beginning inventory Material - 0% Conversion - 75%  | 
3600 | 0 | 2700 | 
| Started and completed currently | 7400 | 7400 | 7400 | 
| Units in
ending WIP Material - 100% Conversion - 20%  | 
3000 | 3000 | 600 | 
| Total units accounted for | 14000 | 10400 | 10700 | 
| Department G | |||
| Computation of Cost per Equivalent unit | |||
| Particulars | Total cost | Material | Conversion | 
| Current period cost | $171,200.00 | $83,200.00 | $88,000.00 | 
| Equivalent units | 10400 | 10700 | |
| Cost per equivalent unit | $8.00 | $8.22 | |
Cost of units started and completed = 7400 * $8 + 7400*$8.2243 = $120,060
Hence option d is correct.
