The Missing Dollar

Three men go to stay at a hotel and they are charged $30 for the room.

They split the cost with ten dollars each.

Later the manager finds out that the rate is $25 and gives the bellboy $5 to return to the guests. On the way to the room the bellboy reasons that $5 would be difficult to split 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 another $2, adding up to $29. Where is the missing dollar?

Locked Store Room

Since only you have the key to the store room and you live alone, the police suspect you as the murderer. You can’t understand anything when suddenly a thought strikes your mind. There is a possible way using which the dead body could have been placed by someone else.

Can you find that way so that you can tell the police and prove yourself to be innocent?
