This Did not rack my brain too much trying to figure this out, but rather the many of the ways this could be figured out!
Way 1 is to just pick it apart, treat the hotel, the boy, and the men as three separate equations where the hotel has 25, the boy has 2 and the men
have 3. Not exactly a way to figure out where the math went wrong, but it does assure you that it did.
Another way is to say each man paid 8.33 to the hotel, .66 to the bell boy, and 1 to themselves.
The way to find the fallacy in the math is to note that 27 is not the total room bill, but rather the amount less the men have at the end of the day.
. 9x3 is very well 27, the amount they now believe is paid to the hotel, and they hold in their hands the 3 required to equal the original 30.
It's about not getting tripped up about the bell boy having 2 dollars, because the 2 dollars is still a part of the bill to the men... realizing
that 27 is a good number to go off of when you realize it includes both hotel cost, and bell boy pocketing, then we already know where the last 3 are!
