Question on valuing opening work in progress: FIFO method

If 7,000 we completed an transferred, and 2,000 were in opening WIP, then it means that the remaining 5000 were started and completed during the period. I do suggest that you watch our free lectures on process costing where this is explained. (Our free lectures are a complete course for Paper F2 and cover everything needed to be able to pass the exam well)
