Answer:
Total equivalent unit 68,000 units
Explanation:
Item equivalent unit
Opening inventory 70% × 4000 2,800
Fully worked units 100% × 61,000 61,000
Closing inventory 60%× 7000 4200
Total equivalent unit 68,000
Notes
1. DOC for opening inventory is 70% i.e 100%-30%. Remember that 30% work has been done in the previous period, so the balance is to be done in this current period
2. Fully work represent the units of inventory introduced in the current period and completed in the same period. Meaning 100% work was achieved in the period.
3. Closing work is only 60% completed. This represent work started this period but not yet completed.
