This book consists of 75 utterly original and totally tantalizing brain teasers from master puzzler George J. Summers. He brings out fascinating challenges in.

Finally determine the specific types of crime committed by each person. J"a u"'ll aul!. J fo GadAI a. This situation contradicts [3]. So Adrian orders only pork. Then, from [2], Carter orders only ham.

So only Buford could hIlve ordered ham yesterday, pork today. If Val's father were Chris, then Chris' sibling would have to be Lynn. Then, from [2], Lynn's daughter would have to be Val. This relationship is incestuous and is not allowed.

So Val's father is Lynn. Then, from [2], Chris' Sibling is Val. So Lynn's daughter is Chris. Then, from [1], Val is Lynn's son. Therefore, Chris is the only female.

So, from [2], the division of the number of nurses according to sex must be such that the number of males is less than six. From [3], the number of female nurses must be less than the number of male nurses. So there must be more than four male nurses.

So there must be no more than nine nurses, consisting of five males and four females, and there must be no less than six male doctors. Then there must be only one female doctor to bring the total to If a male doctor is not included, [2] is contradicted. If a male nurse is not included, [3] is contradicted. If a female doctor is not included, [4] is contradicted. If a female nurse is not included, no fact is contradicted; so the speaker isfemale and is a nurse.

From [7], Freeman will not marry Ada or Cyd.

From [2], [5], and [6], either Cyd or Deb must have the same occupation as Bea and Eve; so Bea and Eve are secretaries. From [7], Freeman will not marry Bea or Eve.

By elimination, Freeman will marry Deb, who must be over 30 and a teacher. The remaining characteristics of the other four women can be determined from previous reasoning. Eve must be under 30 and Bea must be over Cyd must be a secretary and Ada must be a teacher. G, H, and I represent different digits; so one number was carried from the right-hand column to the middle column, and a different number was carried from the middle column to the left-hand column. The only column sum, less than or equal to 27 for which this is true is It follows that FGHI equals What triplets of different digits result in a sum of 19, with no digit in the triplet equal to zero, 1, 2, or 9?

So A represents 8.

The two possible additions are: From [5], if Annette is rich she is artistic. From [1] and [2], if Annette is neither rich nor intelligent she is artistic. So, in any case, Annette is artistic. From [4], if Claudia is beautiful she is artistic.

From [5], if Claudia is rich she is artistic. From [1] and [2], if Claudia is neither rich nor beautiful she is artistic.

So, in any case, Claudia is artistic. Then, from [1], Bernice is not artistic. Then, from [4], Bernice is not beautiful. So, from [1] and [2], Bernice is intelligent and rich. Then, from [1], Annette and Claudia are both beautiful.

Then, from [2] and [3], Annette is not intelligent; so, from [1], Claudia is intelligent. Then, from [1] and [2], Annette is rich and Claudia is not rich. So Alice is the tennis player. If just five games were played, the winner of the round would have won the first, third, and fifth games, from [2]. But from [3], [4], and [5], each man would have been the dealer for one of these games. This situation contradicts [6], so exactly six games were played. Since exactly six games were played, Charles was the dealer for the last or sixth game, from [3], [4], and [5].

From [1], the winner of the last or sixth game won the round; so, from [6], Anthony or Bernard won the last or sixth game and, thus, the round. If Anthony won the sixth game he could not have won the first game or the fourth game, from [6]; nor could he have won the fifth game, from [2].

Then he could only have won the second and third games, a situation which contradicts [2]. So Anthony did not win the sixth game. Then Bernard must have won the sixth game and, thus, Bernard won the round. There are four possible sequences of wins as shown below A represents Anthony, B represents Bernard, and C represents Charles.

S9 So there are six possibilities for the values of A, B, C, and D; the possi-bilities are shown in the chart below.

CB D A a 37 1 3 b 37 2 6 c 37 3 9 d 74 2 3 e 74 4 6 f 74 6 9 Since each letter represents a different digit, possibilities a , c , and e are immediately eliminated. DOing the actual multiplication in b , d , and f to determine E, F, and G in each case, one gets: So D represents 2.

If both [2] and [4] are true, then Curtis killed Dwight and, from [I], statements [5] and [6] are both false. But if Curtis killed Dwight, [5] and [6] cannot both be false.

So Curtis did not kill Dwight. Then, from [II], it is impossible for just one of statements [1], [3], and [5] to be true, as required by [I]. So [1], [3], and [5] are all false and [6] is the other true statement.

Since [6] is true, a lawyer killed Dwight. Since Curtis did not kill Dwight from previous reasoning, Barney is not a lawyer because [3] is false, and Albert is a lawyer because [1] is false it follows that [4] is true, [2] is false, and Albert killed Dwight.

However, the spots for two, three, and six can have either of the following orientations: If die B were like die A, the two on die B would have an orientation opposite to that shown. So die A and die B are not alike.

If die C were like die A, the three on die C would have an orientation opposite to that shown. So die A and die C are not alike. If die C were like die B, the six on die C would have an orientation the same as that shown.

So die A is different. Assumption [1] cannot be applicable because Beth's statement cannot be true under its application.

So assumption [2] is applicable. Since assumption [2] is applicable, Beth's statement cannot be false; so only Anna's statement is false. Then the manner of Cora's death must have been murder. Lancer From [3] and [4], the arrangement around the table could have been only one of the following M represents man and W represents woman: Then, from [1] and [2], the partial seating arrangement was either: Also, a woman could not have sat in chair h in II: Thus, men must have sat in chairs hand g in II.

So, from the above reasoning and from [I], the partial seating arrangement becomes either: Lancer sat in chair c, from [4]. Upon finding a suitable value for F, one then seeks a value for E such that M x E, plus whatever is carried, ends in F. And so on. One finds in a that when M is 2 no value exists for D, and when M is 4 no value exists for D or E; in b that when Mis 2 no value exists for F, but when M is 3 a suitable multiplication occurs.

The multiplication is shown below. If A is 1, then either M or F is 7 and the other is 3.

When Mis 7, both E and Fare 3; but when Mis 3 a suitable multiplication occurs. Then, from [3], Lois' and Dora's hands formed three pairs, Lois' and Rose's hands formed one pair, and Rose's and Dora's hands formed no pairs. So, from the above reasoning, the pairs were distributed as follows A, B, C, and D represent one of a pair: So, after the pairs were removed, Dora held an odd number of cards while Lois and Rose each held an even number of cards.

Thus, the singleton must have been in Rose's hand. Then, from [3] and [4], Betsy's holding must be III. Then, from [3] and [4], Delia's holding must be II. Then, from [3] and [4], Agnes' holding must be I. So, after paying their checks, the women had coins as follows: From [3] and [4], Alan won two sets in the first tournament; then Clay and Earl each won one set in the first tournament.

If Alan won against Earl again, Earl would have to have won against Clay again, which contradicts [2]. So Alan did not win against Earl again but did win against Bart again. Then the winners of the sets in the second tournament are as follows: The sets may be ordered as shown, if the loss of a set is considered as eliminating a player from further competition.

Then B is greater than 4. If B is 5 then G is zero or G is I, contradicting the fact that each letter represents a different digit. Then B is 6, 7, or 8. The possibilities so far, then, are as follows.

Using this information, one finds the above possibilities expand to fifteen in number. So, from [3], the second intern is on call on Sunday and the third intern is on calion Thursday. From [4], the first intern is off on Tuesday. So, from [3], the second and third interns are on call on Tuesday. This information can be put into chart form as shown below X repre-sents on call and - represents off: From [5], the second intern is off on Saturday.

So, from [1], Friday is the day all three interns are on call. The chart may be completed as follows. Open Preview See a Problem?

The great majority of the puzzles which Martin wrote about were logical, mathematical or scientific in some way, but he also loved visual and wordplay challenges.

Over 60 of his puzzles can be found online at the Puzzles. Martin Gardner's Scientific American Puzzle Collections Martin is most famously associated with the puzzles posed in his odd Scientific American columns , and the fifteen resulting books which appeared between and Of course, those columns and books contained much material not in the puzzle vein.

The puzzles that did feature in the Scientific American columns range from being merely thought-provoking to linking to deeper concepts. Here we list the Scientific American spin-offs which focus on items of particular interest to puzzle lovers. In the Preface, he writes, "Robert Weil, my editor at W. Norton, suggested that I select 50 of what I consider my 'best' [Scientific American] columns, mainly in the sense of arousing the greatest reader response, to make this hefty, and in terms on my career, definitive book you now hold.

Mathematical and Logic Puzzles In addition to the 20 main Scientific American books and spin-offs, Martin published about 25 other books of puzzles, some aimed at children. Delightful word puzzles, riddles, and visual illusions are mixed in with "spot the error" headscratchers and teasers about science, knots and counting triangles and squares.

Mathematical results about the graph K3,3, Eulerian circuits, the permutation group on 3 objects, and the maximal number of pieces a disc can be cut into with 4 straight cuts, as well as the pigeonhole principle, are sneaked in unsuspected. Page 26 shows two spacemen exploring the surface of the moon, a full decade before such a thing came to pass.

In the mid s, this book was reworked as Classic Brainteasers Sterling, , 96 pages, illustrated by Jeff Sinclair , with many of the puzzles tweaked. A few years later, the same publisher combined some of this material with excerpts from other books by George J.

Summers, Robert Steinwachs, and Edward J.

Harshman, for Brain Teasers , 96 pages. Science Puzzlers Viking, treated below also has excellent mathematical puzzles.

Then, from [1 b] and [2b], the days of the month each went were: In summary, Arlington has 12 blocks along its border and 12 blocks through it, and Burmingham has 16 blocks along its border and 16 blocks through it.

B s Then, from the possible arrangements derived from [2] and from [5] and [7], situation II becomes: After drawing a card from a second player's hand and discarding a pair, some player would be left with no cards at some point; in that event the third player would draw from the second player's hand when it was her turn to draw.

From [1] and [2], if Claudia is neither rich nor beautiful she is artistic.
