The third part of the Rhind papyrus consists of the remainder of the 91 problems, being 61, 61B, 62-82, 82B, 83-84, and "numbers" 85-87, which are items that are not mathematical in nature.
The final three items on the Rhind papyrus are designated as "numbers" 85-87, as opposed to "problems", and they are scattered widely across the papyrus' back side, or verso.
