Because he knows that if b & c took the caps either black or white it will still remain at least 1 white cap, therefore the cap A wore is white.

While takilg the cap he would have seen the color. This is my suggestion.
Answered By: Senthil Date: 3/8/2008
as there are only two black caps obviously A should be wearing only white cap only then he will be sure about his colour..
Answered By: venkat Date: 3/11/2008
A is standing in front of a mirror. He can see his cap and the color. B cannot see because A is blocking his view. And also, C cannot see the mirror because A and B are blocking his view.

A seen that C having black cap and B having also black cap,according to question there is two black cap and C&B wearing same so A sour that cap colour is white.

white there are four possibilities for A and B i.e WW, WB,BW,BB where w represents white and B represents black since C cant say,so BB is eliminated and B cant say,so eliminates BW.From the remaining two WB and WW so we conform that A hat is white.
Answered By: Govind Kumar Date: 3/29/2008
Possible options when C is not sure
Persons: C B A
Caps: A) N.S B W
B) N.S W B
C) N.S W W
Then B says not sure means option B is ruled out thus A knows he is wearing white.
Answered By: Mahesh Soni Date: 5/19/2008
As A can see what B and C are wearing, He saw that B and C are wearing Black cap. This is the only scenario where he can be sure that he is wearing a White CAP as both the black CAP are wore by A and B.
Hope this solve urs probs.

A is wearing white cap because...when he saw B,C wearing black caps...since there are only 2 black caps...he will be telling that he is wearing white cap...
Answered By: saiprasad Date: 8/19/2008
A may be on mirror side
Answered By: sundar Date: 8/20/2008
Since C said not sure, A & B standing in front must be wearing both White or one black & one white.
Since B said not sure, A standing in front must be wearing White.
So A is sure that he is wearing White.
Answered By: bs shara Date: 8/22/2008
Due to height difference, standing in front of mirror, c is the lowest, b is medium , a is the tallest piece, so i.f.o mirror, B & C can't see the color....... while A can
