following 10 dates:
Mar 4, Mar 5, Mar 8
Jun4, Jun 7
Sep 1, Sep 5
Dec 1, Dec 2, Dec 8
Your boss A told you only the month of his birthday, and told your colleague
C only the day.
After that, you first said: " I don't know A's birthday; C doesn't know it
either. "
After hearing what you said, C replied:" I didn't know A's birthday, but now

| z**********r 发帖数: 24 | 8 我认为应该是 Jun 7 或者 Dec. 2.
原因如下,If C knows the day is 2 or 7, uniquely C knows the birthday of
his/her boss. If you know the month, based on what C said you know the
birthday also.

| X*********n 发帖数: 570 | 9 好好审题. you first said: " I don't know A's birthday; C doesn't know it
either. "
你知道C肯定不知道 所以就不能是六月或者十二月 否则如果是6/7或者12/2 C就上来
就知道了
