Inventory

In R17 EOC Q.13, we see that inventory consists of Finished goods, raw materials and work in progress but the very same vignette then has a note regarding total inventory balance(Note 2 in the Additional info) and the balance for inventory given is very little compared to the sum of Finished goods, raw materials and work in progress. This would mean that only a small fraction(e.g. Raw materials) is actually being contributed as inventory?
