Eight women, including Ms Irwin, went into a department store to buy one item each. Each went directly to the floor where the item she needed was sold, made the purchase, and left immediately. Two items were sold on each of the store’s four floors (ground floor through fourth floor). Can you find each woman's full name (one was named Grace), the item she bought, the floor it was sold on, and, in the cases of the women who left the ground floor and how each arrived at and left the floor of their purchase? (1) The three women who used the escalator at least once were Elsa, Ms King, and the woman who bought the oil painting; (2) The dress and the radio were sold on the same floor; (3) The three women who used the elevator to get both up and down were Delia (who bought the lamp), Ms Long, and the woman who bought the radio; (4) Ms Nelson got her item on the fourth floor; (5) Clara did not buy the ring. She and Beth went to the same floor; (6) The three women who did not use the elevator at all were Elsa, Ms Miller, and the woman who bought the coat; (7) Helen used both the elevator and escalator; ( The woman who bought the linens went down by escalator; (9) Ms Jonas and Alice took the elevator to their different floors. Flo and the woman who bought the books took the escalator up together, since they were going to the same floor. All four rode down on the elevator at the same time and met Ms Perkins as she entered it on the ground floor; (10) The only woman to use the stairs was Ms Owens, who did not make her purchase on the third floor

“We’ve just been discussing our health,” says A, “and we’ve

discovered that between us we share the same five complaints, and the same prescribed tablets for them. Each of us has two complaints, but no two have both the same, and no more than two of us take each sort of tablets. For instance two take red tablets, two blue, and so on. I don’t have green ones. I take one lot the same as E, but they are not yellow, and I do not take kidney tablets.”

B says, “I don’t have green tablets. One heart patient also has tablets for sleeplessness.” C says “I don’t have kidney tablets. I take one lot the same as E which are not for the heart. I don’t take blue ones.” D says, “I don’t have heart trouble. My tablets are not yellow. Those who take green tablets do not also take blue ones.” E says, “I take white tablets which are not for the heart. The ones with nerves do not have indigestion, and nerve tablets are not yellow.”

What colour are the heart tablets? Who takes them for nerves?

Let's say you're a big fat explorer who's camped in a jungle next to a river. Let's also say that you're a curious little dude who wants to know things which are none of your business – one of them being what's upstream except for more water flowing downstream. Lastly, let's say you can paddle a boat like there's no tomorrow.

Problem # 16

Place a Jack (J), a Queen (Q) and a King (K) on three slots in a row like JQK (J on extreme left, K on extreme right). Reverse the position of the cards (ie, KQJ) in the least possible number of moves. In a valid move, a card can be moved either left or right into an empty slot or placed onto a card of a higher rank. (eg, a J can be placed on a K, but not vice-versa). Also, only the top card of the stack can be moved. Now, what is the least

number of moves required if: (a) there are only three slots? (b) there is an empty slot to the left of the Jack? (c) there is an empty slot to the right of the King?

Problem # 17

An independent survey conducted in a large school indicated the lying habits of the students were as follows (category / percentage of students / percentage of lies told of all statements made): (A) Truthful students / 10% / 0%; (B) Students who seldom lied / 20% / 20%; (C) Students who evenly lied / 50% / 50%; (D) Students who frequently lied / 20% / 80%; (E) Students who were liars / 10% / 100%.

The same group of students were given a multiple choice questionnaire and were asked to indicate the category (A, B, C, D, or E) which they belonged to. Obviously students would indicate their category, depending upon their nature – eg: All truthful students would put themselves in category A, but Liars would never indicate category E. The problem is, what would be the percentages of students in various categories as self indicated by the students? Further if a second self-assessment survey is conducted asking the students whether they had truthfully answered the first self assessment survey having only two categories (T) Told the truth, and (F) Lied, what would the results tell in percentage terms?

PRBLM#30Arjun is playing the videogame Space Squeakers, and he finally loses his last turn after several hours (and after killing numerous invading space mice). He was rather surprised to discover that he had scored the maximum number of points he could have while averaging exactly 9975 points per turn.

If in Space Squeakers you start with 3 turns and you earn an extra turn with every 10000 points you score (e.g. you earn an extra turn at 10000, another at 20000, another at 30000 etc.), what was Arjun's final score?

Problem # 31

Last week, six fourth graders--three girls (Allison, Linda, Maria) and three boys (Drew, Eric, Mike)--played a two-hour game of Monopoly, with five going bankrupt and the winning sixth declaring "Monopoly!" Each player used a different one of the metal tokens, and each managed to buy one set of like-colored properties, one owning Orange, which he or she improved with houses and/or hotels. Given the clues below, can you "Pass Go" by determining the full name (one last name is Short) of each player, the token he or she used during the game, the set of properties he or she owned, and the order in which the five losers went bankrupt to leave one winner?

1. Eric went bankrupt immediately before the player who bought Marvin Gardens and the other Yellow properties did; the child who used the Battleship token was still in the game after they were out.

2. The Parker boy didn't own Pacific Avenue and the other Green properties.3. Drew didn't win the game.4. The Green properties weren't in possession of the player who had the Battleship

token.5. Allison immediately preceded the player with the Top Hat token into bankruptcy.

The Chance girl, who didn't have the Battleship as her playing token, went out of the game immediately following the player with the Top Hat token.

6. Maria isn't the player who moved the Thimble token around the board.7. Right before the person who owned Illinois Avenue and the other Red properties

went out of the game, the player with St. Charles Place and the other Purple rentals went bankrupt.

8. Eric didn't buy the Green properties9. These three players declared bankruptcy in consecutive order first-to-last: Linda,

the Parker child, and the one who owned the Blue properties, Boardwalk and Park Place.

10. The Reading child once landed on Indiana Avenue, one of the Red properties, and had to pay rent to another player for the two houses on it.

11. Neither the player who had the Flatiron nor the one who used the Thimble as a playing piece purchased the Purple properties.

12. The player with the Automobile token went bankrupt right after Mike did; both lost when they landed on Green properties and couldn't pay the rent.

13. The Waters boy didn't play with the Top Hat as his token.14. The Baltic child, who didn't own the Red trio, and the player who had the Cannon

playing piece both drew "Get Out of Jail Free" cards.15. Linda, who didn't buy the Green properties, and the player who used the

Automobile token each owned one of the utility companies in addition to a color property set.

As part of a fundraiser to help cure cystic fibrosis, members--four men (Jeff, Rob, Tom, and Wes) and three women (Beth, Faith, and Sue)--of the Super Cyclists rode the 300 miles from Summerset to Ocean City. Each of the seven rode one leg of the distance, with riders changing in different cities--one being Autumndale--en route. Given the log of the relay below, can you solve this 5-star Logic Puzzle by finding the starting and ending points of each leg (Summerset starts the 1st and Ocean City ends the last), the mileage covered during the leg, and the full name (one last name is Young) of the cyclist pedaling that distance?

1. The shortest leg covers 20 miles and the longest 75; no two legs are the same distance.

2. Price's ride ended in Bayview.3. The 1st change of riders didn't occur in Fort Hill.4. Wes rode 10 miles farther than Jeff did.5. The leg Tom pedaled is 25 miles longer than the leg going from Glen Falls to

Central City and 50 miles longer than the distance Ms. Dunn covered cycling her leg--which isn't the shortest.

6. The last leg is 15 miles shorter than the one Koontz covered.7. Ives rode neither the 1st nor the last relay leg.8. Mr. Price rode 10 miles farther than the cyclist who rode the 1st leg, which isn't

the 20-mile-long one, but pedaled 20 fewer miles than Rob did completing his leg.

9. Moore didn't ride the last leg into Ocean City.10. The leg starting in Fort Hill is twice as long as the leg ending in Fort Hill.11. The ride ending in Glen Falls is the longest.12. Beth didn't ride the shortest leg.13. Ms. Dunn started her part of the relay in Mt. Holly.14. Ms. Close pedaled twice as many miles as Faith did.15. Rob's leg didn't start in Central City.

Problem # 33

An independent survey conducted in a large school indicated the lying habits of the students were as follows (category / percentage of students / percentage of lies told of all statements made): (A) Truthful students / 10% / 0%; (B) Students who seldom

lied / 20% / 20%; (C) Students who evenly lied / 40% / 50%; (D) Students who frequently lied / 20% / 80%; (E) Students who were liars / 10% / 100%.

The same group of students were given a multiple choice questionnaire and were asked to indicate the category (A, B, C, D, or E) which they belonged to. Obviously students would indicate their category, depending upon their nature – eg: All truthful students would put themselves in category A, but Liars would never indicate category E. The problem is, what would be the percentages of students in various categories as self indicated by the students? Further if a second self-assessment survey is conducted asking the students whether they had truthfully answered the first self assessment survey having only two categories (T) Told the truth, and (F) Lied, what would the results tell in percentage terms?
