You know the COGS (cost of good sold), opening stock + purchases - closing stock. What are the opening stock closing stock, will all of the opening stock be under the heading of opening stock, will all purchases be under that heading or?
yes, or sometimes it'll just say COGS:..... but yes, normally if theyre asking you to calculate cogs, they will give you opening stock, purchases and closing stock.
alternatively, they could give you sales, and gross profit, allowing you to work out COGS from that.
