Math!!! It Isn't So Straightforward
Ok, here goes...
Math seems pretty straightforward. And it's either simple calculations or complex ones. But there is always a solution...Or is there!!!
Let's try this. (figures are just examples and are not reflective of any rates. *grin*)
3 guys who were traveling stopped at a motel for the night. They got a not-so-expensive room for themselves, which cost them $30. So each guy had to shell out $10. This seemed to be a good deal for a stay there.
Just before checking out in the morning, room service came by and told them that the manager had given them a $5 discount. He returned the same to them. The 3 guys each took $1 back and tipped the room service guy with the remaining $2. And off they went headed back home.
Now let's go back and calculate the equation!!!
Each guy 1st spent $10, but took back $1 later. So in the end each spent $9. So 3x9=27. And the room service guy was tipped $2. So 27+2=29.
Hmmmm!!! $29 has been accounted for. So where is that remaining 1 dollar???
Math!!! Simple, but sometimes, complicated, or shall we say, Mind Boggling!!!

This is another approach which is more LOGICALLY sound.
10x3=30
(10x3)-5=30-5 add in $5 discount
((9+1)x3)-2=(27+3)-2 each guy gets $1 back and the tip is $2
30=30 simplify
Don't forget, numbers don't lie. People lie. 4/20/2011
Does anybody know what the flaw in this guy's logic is? I know it's wrong, but I can't see where it's wrong.
