Solve This Tough Riddle
Three soldiers are standing in a line front to back like so:
A - B - C
<--
All of them are facing to the left.
Soldier A can't see anyone. Soldier B can see soldier A and soldier C can see soldier A and soldier B. Soldier A has a red tag on his back. Soldiers B and C have blue tags on their backs. Each soldier does not know what color tag they have on their back. They cannot turn around. They cannot talk to each other.
The drill sargeant tells them that one of them must shout out what color tag is on their back with in 5 minutes. If they fail or guess incorrectly they will be severely punished. He also says that the quicker they get it will determine whether or not they are punished lightly or rewarded, so basically the sooner the answer, the better. He also tells them that different colored tags have been placed on their backs. Some may be blue some may be red. He also tells them that two of them are wearing the same color and the other is wearing a different color.
After 1 minute, one of the soldiers yells out the color of the tag he is wearing and is correct.
Tell soldier this was and explain his reasoning for guessing the answer that he chose.
This is a logic riddle, the answer isn't, "He just guessed" or some stupid answer like that, it will make perfect sense when you hear the answer.
Hint, the soldier couldn't have guessed the answer correctly without waiting at least a minute.

Its soldier B
REASON: B knows that there's blue & red tags, and knows A is red, abd C can see both B and A's tags. Since he realised that C isn't answering, A and B has to be different colours. Since B sees that A is red, he knows for sure that he is blue

Yes t_o_g thatīs right. Soldier B waits a little bit, because he knows, that there are two of the same colour and soldier c doesnīt scream out his colour, so he knows that a and b doesnīt have the same colour and he can see the colour of a, therefore he knows his colour.
BTW, there is a thread called "riddles", where you can post more of these good oneīs
edit: I see, you have posted your reason for the solution at the same time i did

The interesting thing is that poor A soldier who sees nothing can name his color after B named one. But the C, who sees both colors and seems to be the luckiest from the first glance, will get all the punishment, for he can only guess his color!

What I don't get is why did he have to wait a whole min? I mean if C didn't shout out the answer in the first 10 seconds he should have known...lol
