Explanation:

- Let's break down the sequence of purchases:

- There are five persons: A, G, K, L, and S.

- G purchased immediately before K.

- Two persons bought between A and the one who bought the chair.

- S does not buy a wallet.

- Three persons bought between the chair buyer and the table buyer.

- Two persons bought between the wallet buyer and the table buyer.

- Bag is purchased immediately before perfume.

- Two persons bought between L and the one who purchase perfume.

- We need to place the purchasers in a sequence that satisfies all conditions:

- G and K must be consecutive.

- We can deduce that: A, _, chair, _, _, table; here, two people between A and chair, three between chair and table.

- G and K cannot be on chair, thus they may be on positions like G, K, _, chair, _, table.

- Possible Sequence could be: L (bag), K (perfume), G, A, chair, wallet, S, table.

- Therefore, S purchases last.

- S purchases the item last.
