Which practice ensures oldest stock is used first?

• A. Using oldest stock first.
• B. Using newest stock first.
• C. Rotating stock based on color.
• D. Keeping all stock at the back.

Answer: (A)

This is about using stock in First-In, First-Out order. FIFO keeps older items from sitting and potentially expiring, which protects quality and minimizes waste. By using the oldest stock first, you ensure items with the earliest dates are consumed or sold before newer ones, which is especially important for perishable or time-sensitive goods.

If you were to use newer stock first, the older stock might sit unused and become unsellable or unsafe. Rotating stock by color isn’t reliable because color doesn’t reliably indicate age or expiration dates. Simply keeping stock at the back also doesn’t guarantee that the oldest items get used first.
