Three men walk inside a hotel and decide to stay for the night. They pay the price of $30 by splitting it so they each pay $10. They go up their room, but then the manager realizes that the price that night is $25 dollars so he sends $5 dollars up with the bell boy. The bellboy realizes that $5 can't be split by 3 so he pockets $2 and gives the men $1 each. But if you calculate it, the 3 men each payed $9, and 9 times 3 is 27, then add the $2 from the bellboy you got $29. Where did the last $1 go?
A very old problem
"But if you calculate it, the 3 men each payed $9, and 9 times 3 is 27, then add the $2 from the bellboy you got $29"
What are you "calculating"
$9x3 = $27 deals with the cost of the room
you are then adding $2 which has nothing to do with the room cost.
You are adding "apples and oranges"
2 apples + 3 oranges = 5 ???(5 what?)
the real calculation should have been
amount paid - cost of room = left over money
$27 - $25 = $2
