IQ test
Quite an interesting IQ test here .... A lot ppl may already seen it before. The guy who posted it in a forum stated that you need IQ 140 and above in order to answer it. Well, it is not that tough anyway, got it solved in 2mins. Btw my IQ is way below 140... =P. So this is how the question looks like: P and Q both know that there are 16 cards inside a box. They also know the suits and numbers of the cards. Spade : J, 8, 4, 2, 7, 3 Heart : A, Q, 4 Club : K, Q, 5, 4, 6 Diamond : A, 5 R pickup a card from the box. He only tells P about the number and Q about the suit. Simple question , which card? P : I don't know. Q : I knew that you don't know. P: Well, I got it now. Q: Hmm... I also got it now. So which card ?
