If the answer to this question  problem 85 in Mr. Friedlands collection  seems obvious  then perhaps you should stop to reflect a bit  for the correct answer may astound you. The book presents  for the alternate consternation and satisfaction of the reader  fully 100 intriguing problems based on permutations and combinations  properties of numbers  algebra  geometry  and logic. All the problems are posed in the form of stories  and all require of the puzzle-solver the same curiosity as the protagonists in Mr. Friedlands little stories. You should approach each of these problems carefully  for elements of challenge and surprise are built into every one  and all are sufficiently difficult to tax the wits of the inveterate puzzle-solver.Though none of the puzzles here requires any more mathematical knowledge than high-school algebra and geometry  problems are sufficiently difficult to provide hours of enjoyment for the more mathematically proficient. Moreover  the author has tried to create entirely original problems  so it is highly unlikely that you will find any you have encountered in other collections. Concise solutions are provided.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":45921798914101,"sku":"ByrdShop_048622256X","price":64.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8139\/0901\/files\/9780486222561.jpg?v=1787603529","url":"https:\/\/atxbooks.com\/products\/puzzles-in-math-and-logic-dover-recreational-math-9780486222561","provider":"ATX Books","version":"1.0","type":"link"}
