You're still telling it as a narrative. If you wrote it out as an Excel spreadsheet, I think the difficulty would vanish.

Spreadsheet?? Just look at it this way: where is the money? The guests have paid $27, of which $25 is with the innkeeper and $2 is with the bellhop. Problem gone.

The aim of my post is to point out that there is no difficulty until the riddler leads you into thinking there is. Nonetheless, you could do:

1) A: $0, B1: $10, B2: $10, B3: $10, C: $0

2) A: $30, B1: $0, B2: $0, B3: $0, C: $0

3) A: $25, B1: $0, B2: $0, B3: $0, C: $5

4) A: $25, B1: $1, B2: $1, B3: $1, C: $2

And then misdirect by saying "But," then stating,

[B1(1) - B1(4)] + [B2(1) - B2(4)] + [B3(1) - B3(4)] + C = 29

and then asking "Where'd the missing dollar go?"
