Just got this from a friend. trying to verify my answer.

One day two students, Mr. P and Mr. Q are doing a test with Prof John.

They know there are 16 cards in the drawer,
Heart:   A Q 4
Spade:   J 8 4 2 7 3
Club:    K Q 5 4 6
Diamond: A 5

Prof John drew one card from the group. He told Mr. P the face value of the card and told Mr. Q the suite of the card.

Here is the conversation between them,

Prof John: Do you know which card it is?

Mr. P:    I cannot tell which card it is.

Mr. Q:    I know you cannot tell.

Mr. P:    Based on what you just said, I know which card it is now.

Mr. Q:    Well, I also know which card it is now.

What is the card and give your reasoning.
