PSE gets an annoyingly large number of questions from people who are very clearly trying to cheat on aptitude tests. It is possible that I was too hasty in guessing that this was one of them. But consider the warning signs:
The fact that the question is old (which I confess I didn't check) is no guarantee of honest intentions, though; surely questions like this get reused sometimes.
However: I concede that I was only guessing that you were trying to cheat on an aptitude test. I may have guessed wrong.
There were, I'm afraid, other reasons for closing the question. (The process of closing requires us to specify just one.)
- It was posted without any indication of where it came from. As already mentioned, you're not allowed to do that here: creators of puzzles (even bad ones) deserve credit for their work. Of course, that can be fixed by editing the question to say exactly where it's from.
- It is also official policy here that we don't allow puzzles whose creators have asked them not to be shared. It seems unlikely that the source you cited is actually the original source of the puzzle, but the text bobble quoted indicates that they, at least, specifically instruct readers not to post their material elsewhere.
- It's really not a puzzle in any useful sense, so far as I can tell. I can't summon up the patience to read its wall of text in full detail, but it looks as if either (1) if you go through and parse all the details one of the options is demonstrably better than the others (in which case it's basically mathematics, just very boring mathematics, and would be closed as being a mathematics problem rather than a puzzle) or else (2) you're being asked to exercise your judgement about something like "would I rather have £100 or an airline ticket whose nominal value is £200 but for a trip I might not actually want to take?" (in which case it's just not a puzzle and would be closed as "opinion-based").
So, if I were to reopen the question as "maybe not a mathematical problem after all", my next action would be to close it again as "a puzzle you found elsewhere without proper citation of its source".
If you edited into it the link given in this question, then (aside from my concern that that's clearly not the actual origin of the question) I might reopen it since it would then be properly attributed -- but I would then immediately have to close it again as "a puzzle whose creator has asked for it not to be shared".
If you got permission from the relevant people to post it here, then maybe it would be necessary to figure out the intended solution and whether it's actually a matter of calculation or judgement; and then we would immediately have to close it again either as "mathematical problem not puzzle" (after all) or "opinion-based".
What I don't see is any plausible way that it remains open. It just isn't the sort of thing PSE is for.
