Average Cost Inventory Method

This problem practices a core inventory accounting concept, how companies assign product costs when units are indistinguishable or purchased over time at different prices. Candidates need to understand the logic behind weighted average costing and how it differs from methods that track specific purchase timing, because interviewers often test whether you can explain the mechanics of financial statements and the tradeoffs between different accounting methods.

It also checks whether you can think about when a method is appropriate in practice. In banking interviews, questions like this are used to see if you understand how inventory choices affect reported margins, earnings, and comparability, and whether you can connect accounting rules to real business situations.
