Classic Lateral Thinking Puzzles

A man writes the same number, and nothing else, on 20 sheets of paper. Why? To figure this out--and hundreds of other mind-bending lateral puzzles, too--you'll have to really fire up your brain and imagination. At first, it may not seem as if there's enough information to come up with a solution. But look more closely; there's always more than meets the eye. Check your assumptions, ask good questions, retune your mind, separate the facts from the red herrings, and the answers will come.Harshman, Edward J. is the author of 'Classic Lateral Thinking Puzzles' with ISBN 9781402710629 and ISBN 1402710623.
