An Apple a Day Keeps the Riddles Away
There are 20 people in an empty, square room. Each person has full sight of the entire room and everyone in it without turning his head or body, or moving in any way other than the eyes. Where can you place an apple so that all but one person can see it?

Put it on the head of one of the people standing in the roomReplyDelete
As bookish said it, place it on a person's head.ReplyDelete
I think it would have to be on the head of someone standing in one of the corners.ReplyDelete
That's right. As long as there are no mirrors in the room, the person who has the apple on his/her head cannot see it.ReplyDelete
the apple is on his head. Everyone sees it but himReplyDelete
