That explanation is not consistent with the claim You don't need math skills to solve this, only problem solving skills. I'm just saying, it'd be nice if there is a warning when something that looks like a standard lateral thinking brain teaser is actually the topic of a paper submitted by a pair of professors of mathematics to the 2003 Conference on "Compexity".
