brain teaser to refresh trader's mind
Posted: Tue Apr 14, 2015 6:33 pm
and for those who have the solution and are bored now, a little twist: does Albert know the birthday or not if the conversation goes like this?
- Albert: I know that Bernard doesn't know
- Bernard: gosh, I still don't know
- Albert:
and after Albert says if he knows or not, does Bernard
1) finally know
2) doesn't know, or
3) could either know or not know?
