In one Lone Wolf gamebook you are tasked with solving a demoness's riddle and turning to the section with the same number as the answer. While the answer can be found by flipping through pages to find the appropriate section, nobody has yet come up with a satisfactory way to get the answer from the question. Looked at mathematically, the question is insoluble, asking the player to derive a variable without enough information to do so. It's likely the author just messed up the maths.
