Re: riddle of the day (a good way to win a free beer)
[quote=imported_cneill]Right, the riddle leads you in an illogical line of thinking. Think about it this way and try to make sense of the math:
You each paid $10 (equalling 30 total), but you each got back $1, so in the end you each only paid $9 (27 total), which leaves $3, but the bellhop only kept $2, and 27+2=29. But you started with 30.. How do you explain that?
I think it probably works better in verbal form at a bar. People start scribbling math on napkins, some blurt out wrong answers, and everybody just confuses each other. When you see it written down it's easy to see right through it.[/quote]
Hmm, here is how I thought it:
Each one pays 9 dollars.. so the girl (I was imagining her as a 30 year old girl with a white shirt, glasses and umm.. how do you call it.. brown hair, well but that doesn?t matter) gets 27 dollars (after giving back 3). As the room costs 25$, she gets 2 for herself and the other 25 go in the ..err.. cash box
The "trick" of the whole matter is that you are adding 27 (all the cash she has in her hand) with 2 (the cash she also has in her hand and that she is going to keep), while you should be adding 27 (the cash she has got, 25 for the hotel and 2 for her) + 3 (the cash she gave back) to get to the whole 30 dollars.
Hope I made it somewhat clearer, my english isn?t very good I know :S
