A teacher writes six words on the board: cat, dog, has, max, dim, tag. The teacher hands a piece of paper to Albert, another to Bernard, and another to Cheryl. The teacher explains each paper contains a different letter from one of the words written on the board. The teacher asks if Albert knows the secret word, and *after a moment, he replies aloud, "Yes." The teacher then asks Bernard, and after a moment of thinking, he also says, "Yes." And finally Cheryl is asked and she takes a moment and then confidently replies, "Yes," she also knows the word. Albert, Bernard and Cheryl always ace their logic exams. What was the secret word? Watch the video for the solution.

*Since the original wording caused confusion, I meant to say each person takes a moment to think. As written in the video there was room for interpretation--if I were grading I would have accepted any logically reasoned conclusion.

I adapted this problem from the puzzle "Yes, Yes, Yes" in "The Great Book of Mind Teasers & Mind Puzzlers" by George J. Summers, which has the same situation with 5 words.

This puzzle has been featured on Mental Floss, Reader's Digest, and MSN:
