It's not explicitly explained how the Inner Tower, Outer Tower and Middle Area are connected and interact, we just have to accept that they are and they do.

Rankers (and by extension, their associates) can skip Floors of the Tower by travelling up/down the stairways in the Middle Area. It is extremely likely that this was how Anak was taken to this Floor in the past. I think it was said somewhere that Anak lived in the Middle Area while she was on the 43rd Floor (but don't quote me on that since I'm not sure of it myself). But the Middle Area and Outer Tower are both plausible places.
