lol i got confused a little in the begining but i found how simple it was after.

the bellboy has \$5 and he gave each of the three people \$1. Which would be \$5 - \$3= \$2.

so the one of the three guest has the remaining dollar.

\$25 for room + \$2 for bellboy + \$3 back = \$30

its supposed to be \$28 for the group
30 - 5 = 25 + 3 = 28 +2 = 30

Three people check into a hotel. They pay \$30 to the manager and go to their room. The manager finds out that the room rate is \$25 and gives \$5 to the bellboy to return. On the way to the room the bellboy reasons that \$5 would be difficult to share among three people so he pockets \$2 and gives \$1 to each person. Now each person paid \$10 and got back \$1. So they paid \$9 each, totalling \$27. The bellboy has \$2, totalling \$29.
Where is the remaining dollar?

He takes the five dollars & gives three back to the people \$25 + \$3 = \$28 + the \$2 pocketed = the original \$30

this shows it better:

10+10+10=30=25+2+3 giving the \$3 back gives =>

10+10+10+(-3)=30+(-3)=25+2+3+(-3) or

10+10+10-3=27=25+2

each person actually paid \$9.33 each for the room, so the \$1 is with the desk clerk

This is a great one. I learned it as a kid 40 years ago. It is simply bad logic. There is no missing dollar. You cannot figure that each person paid \$9.00, they did not. The three of them paid a total of \$25.00 and they then got a dollar each back and the bell hop still has two. Total of \$30.00

It's just how you write the math at the end that makes it so confusing, Each man paid 10 so 10 10 10 then subtract 25 (what the manager kept) and then subract 5 (what the bellboy had) and you equal 30. Sometimes working something backwards makes it easier.
