RR or RW or WW
Cheif hide both white one i.e WW
So now there remain two RR and one W
so peron having White band can easliy identify that. So simple.
If Cheif hide RW
So now there remain two WW and one R
in this case two who can see red will say they have got white since he cannot have "R"
If cheif hide bot red i.e RR
then we have three white bands
So now if no body is answring means they all have white so after some time one can definetly answer white
then one will easily say tha he has got White since
Three Palefaces were taken captive by a hostile Indian tribe. According to tribe’s custom they had to pass an intelligence test, or die. The chieftain showed 5 headbands – 2 red and 3 white. The 3 men were blindfolded and positioned one after another, face to back. The chief put a headband on each of their heads, hid two remaining headbands, and removed their blindfolds. So the third man could see the headbands on the two men in front of him, the second man could see the headband on the first, and the first could not see any headbands at all.
According to the rules any one of the three men could speak first and try to guess his headband color. And if he guessed correctly – they passed the test and could go free, if not – they failed. It so happened that all 3 Palefaces were prominent logicians from a nearby academy. So after a few minutes of silence, the first man in the line said: "My headband is ...".
What color was his head band? Why?
