It could be a child's play for some of you, especially for those who have done a similar problem before. Anyways, if you get the solution post it in the comments !
Three men were taken captive by a hostile tribe. The chieftain was willing to let them go so he took them to a tepee, where there was no light. He put one head band on each of their heads (he had 3 white and 2 red - so 2 head bands were not used). Then they went out in a queue so that each man saw the head-band of those standing in front of himself (the first one did not see any head band, the second one saw the first one's head band, and the third one saw the head bands of the two others). If somebody said the colour of his head-band, they all would be free. After a quiet while one of them said: "My head-band is ...".
What colour was his head band? And how would you reason it?

Too simple? So let's make it a little grown-up type. The one first in the queue wasn't wearing red band !!!

If 3rd (last) guy sees both red, then he will speak immediately.. (his colour as white) if he doesnt speak that would mean 1,2 either have W,R or W,W (not in same order)..
So the second guy (middle) suppose sees 1st wearing red, then he would speak up his colour as white.. if he too keeps quiet then 1st guy would know that he is wearing white...
So overall, first guy would speak his own color as white (provided no one else has spoken)
Right. And that means you can sense the surroundings even if you are blindfolded and you hear no voice. (We could blindfold the first guy.)What would this sense be called?
i dont know wats the name of this sense... tu hee bataa de..
