Okay, here's the question to all who are interested: There are three people and they are blindfolded. Now, they are given one cap each, all of them are given red caps, which they wear, unware what color it is. However, they are told that either they either have a black cap or a red cap and they can see two other's cap once the blindfold is removed. Also, they are told that once the blindfold is removed, and if they see any red cap, they will have raise their hand. Now they open their eyes. One can't see what one is wearing, but can see two other's cap. One of the people their would be able to tell "I am wearing red cap!" logically. How?
