last post of the day. test your brain (:

IQ question:

There are five caps , 3 black and 2 white. three persons chander, sunder and maninder are standing one behind the other in a queue. the first person in the queue is chander and the last person is maninder . 3 caps rfrom the lot of fivce is taken and put on their heads. Maninder can see what the other two standing in front are wearing . sunder can see what chander is wearing. None of them can turn around and see what the person standing behind is wearing , they do not know the color of cap what they themselves are wearing . John comes and asks maninder,"what is the color of the cap your are wearing?", Maninder can see what sunder and chander are wearing, and based on that he says he doesn't know. sunder has over heard that answer. Now john asks sunder" what is the colour of the cap you are wearing". sunder can see chander and he has heard what maninder has said, and based on that he says he doesn't know. chander has overheard both sunder and maninder. so when john asks chander the same question, he tells the correct answer. What is the colour of the cap that chander is wearing ? Please write in brief how did you reach to that conclusion.

answer:

chander=c sunder=s maninder=m
1. if m sees two white caps infront of him on c and s he
would have answered black. when he says he doesnot know that
sures one thing that c and s are wearing combination of
white and black or both black.
2. if s sees a white cap on c he would have readily shouted
black as if his head had white cap then m would have
answered the question, since m didnt. now if he sees a black
cap on c head he again does not know whether his head has
black or white.
3.since s answered doesn't know, c catches the point that he
is wearing a BLACK CAP.


didn't get the answer until i was given the answer.
