Three guests check into a hotel room. The clerk says the bill is £30, so each guest pays £10. Later the clerk realises the bill should only be £25. To rectify this, the clerk gives the porter £5 to return to the guests. On the way to the room, the porter realises that he cannot divide the money equally. As the guests did not know the whole of the revised bill, the porter decide to just give each guest £1 and keep £2 for himself. Each guest got £1 back so now each guest only paid £9, bringing the total paid to £27. The porter has £2. And £27 + £2 - £29 so, if the guests originally handed over £30, what happened to the remaining £1?

Is the porter one of the guests?

It's backwards reasoning based on percentages between the payer of the room and the clerk.
