Re: Another logic riddle
The answer is:
<font color="white"> 7. At the first breakfast, if there is only one BEM, then he will leave because he will look around and not see any BEMs and will know that he must be the one.
If there were two BEMs they will both leave at the first lunch. Each BEM will only see one BEM, but they will know that there must be two because if there were only one he would have left at breakfast.
And so on until the 7th meal when 7 BEMs leave </font>
