Let me have one, and I'll try to solve it. Here's a couple: There is a hotel called the Infinite Hotel. It has an infinite number of floors (we're talking the lower versions of infinity; only countable, whole, positive numbers). If all of the rooms are full in the infinite hotel, and one person comes in and says that he wants a room; what should the front desk person do? Hint: you want to get the guest into a room without killing anyone or having them share rooms. The answer seems pretty obvious to me. [b]SOLVED: by kyuss534[/b] [spoiler]You move every patron of the hotel over one room. Put the new patron in the first room. Official answer: You tell the person in room #1 to move to room #2, and tell the person in moving from room #1 to tell the person in room #2 to move to room #3, and so on. Here's the formula [i]n+1[/i][/spoiler] There is the same Infinite Hotel as above, but this is the manager's worst nightmare. An infinite number of buses with an infinite number of people comes to the fully-booked hotel, all of them wanting a room. What does the manager do to fit all of them in? You must assign them a room. You don't have to get them in all at once. [i]Riddles from Ted Ed[/i] Edit: we're trending! ( ͡° ͜ʖ ͡°) Edit: Holy shit!! 300+!!! Edit: damn this thread is dying... Edit: 1k.
