    This is laughably easy once it's been explained to you. OK it had to be explained to me several times but hey...
    Who can get it the quickest.

    3 men go to a hotel. Receptionist tell them it's £30 for the room. They pay the £30 and go off. The receptionist realises he's made a mistake, it should only be £25, so he hands the bell-boy £5 and tells him to return the money to the 3 men. The bell-boy can't figure out how to divide £5 by 3 so he thinks I'll just give them £1 each back and pocket the other £2.
    This means the 3 men have paid £9 each for the room. 3 x £9 = £27. The bell-boy has £2. That makes a total of £29. Where has the other £1 gone!

    aaarrrrggghhh it's getting late.

    3x£8 is £24. So the extra £1 has gone to the hotel as the bell boy had less than £1 from each person (i.e. £2 to bell boy, £1 to hotel)

    Is that right?

    I won't go as far as asking what the 3 blokes were doing sharing a room. I assume saving money by only having one room. (But maybe that part of the puzzle is irrelevant!)

    3 x £9 does equal £27, but the £2 going to the bell-boy is included in that £27, so it makes no sense to add the £2 to £27 to make £29.
    They paid £25 for the hotel room, £2 for the tip (£27), and then got £1 back each to make the original £30.

    There are 3 lights in the attic and 3 switches in the basement.

    Each switch controls one light but no one knows which one.

    You may only touch the switches a maximum of 3 times in total and may only go up stairs once.

    How do you work out which switch controls which light?

    Turn on switch A. Leave it for a few minutes. Turn it off, and trundle off down to the cellar and have a feel of the bulbs and find out which bulb is warm. Take notes.

    Have a beer, to let that one cool down.

    Wander back upstairs. Repeat for switch B, and by a process of elimination, you know which bulb is controlled by switch C too.

    Have another beer to celebrate.

    Have a third beer while you ponder why on earth anyone would have switches for the cellar lights in the attic.

    Close, but you are only allowed one trip from attic to cellar. Any more would be a waste of effort! (and the electrics were designed by a woman!)

    Fair do's, that was a pants explanation I gave anyway.

    Turn A AND B on, leave for a bit, turn B off, when you go up A is on, B is warm and C is cold.

    That's better!

    Edit: Ye Gods, I'm a cack reader. I missed the one trip thing AND got the floors mixed up first time!

    Yeah, but you came to the same conclusion I did, so it's all good. :D

    Heres an easy one......

    A man walks into the shop and asks how much one costs. the girl serving replies £2, he says what about thirty five and she replies that will be £4 pounds. Finally he says what about six hundred and sixty six and she replies just £6 please.

    What is he buying?

    yup, next.......

    Six drinking glasses stand in a row, with the first three full of water and the next three empty. By handling and moving only one glass at a time, how can you arrange the six glasses so that no full glass stands next to another full glass, and no empty glass stands next to another empty glass. What is the minimum number of moves to solve this puzzle.
  18. sunny_jimbob

    sunny_jimbob Member

    One move - empty the second full glass into the second empty glass.

    One move: take the middle of the full glasses and pour its contents into the middle of the empty ones.

    3 moves.

    move 1. LH glass move to RH end
    move 2. Glass now 3rd from RH end move to LH end.
    move 3. glass now 2nd from LH end move to 3rd from RH end.

    easy peasy.
