Explanation:
The question is incomplete, production figures are missing. We will provide assumed figures in order to illustrate the process of determining units started and completed.
First in First out Costing Method
First in First out Method is a method that controls the flow of inventory. First In First Out Method stipulates that when inventory is sold, we start by selling oldest inventory first. Similar concept is applied in the production process, When we start production in the current period we start with opening work in progress units first before we start producing new units in the current period.
opening work in progress = 5000 units
units started in the current period = 12000 units
Closing work in Progress = 3000
Units Started and Completed = units started in the current period - closing work in progress units
Units Started and Completed = 12000 - 3000
Units Started and Completed = 9000
