On Earth Day, in Wilder Bowl, Emily had 30 tie-dyed t-shirts to sell at the rate of 3 for $20.00. Liz had 30 slightly fancier t-shirts to sell at the rate of 2 for $20.00. Emily suddenly got sick and asked Liz to sell her shirts for her. Liz agreed. Finding the difference in price a bit hard to keep track of, Liz decided to combine everything and sell all the shirts at 5 for $40.00, a reasonable decision. After everything sold out, which it did, Liz dropped off Emily’s $200. But then, to her surprise, instead of the $300 she expected to have left for herself, she had only $280. What happened to the other $20.00?

False Coins 3 (9, ?, 3)
You have nine coins, supposedly made of silver. But one is counterfeit, and you do not know whether it is lighter or heavier than the rest—it is just different in weight somehow. You have three weighings on a 2-pan scale to figure out which is the counterfeit coin and whether it is lighter or heavier.
Highland Island 2 (C, P)
Back on Highland Island once again, you are out for a walk (you take a lot of walks), and you encounter three of the natives. You can’t tell whether each of them is a Chocolate (truth teller) or a Peach (liar). Forgetting that this won’t help you, you ask the first native what he is. He mumbles something that you can’t hear. The second native says, “He says he’s a Chocolate. He is one and I am too.” The third native speaks up immediately: “That’s not true. The first guy is a Peach, and I’m a Chocolate.” Who is what?
Soccer Game Scores 1
Three soccer teams, A, B, and C, all play each other one game. Most of the data from the three games was lost by a careless clerk, including the score of each match. You, as sports editor, are alone in the copy room of the newspaper and must write up the scores of the games. Due to a sudden storm, telephone lines are down and so you will have to figure out these scores from the one piece of paper that the clerk did manage to get to you—and even IT has some figures missing. Use this sketchy information to figure out the scores of the three soccer games.

Horse Trading
Frank sells Sue a horse for $60. Then he decides he wants it back, but Sue makes him pay $70 for it. Then Sue changes her mind and buys it back from Frank, but for $80 (Frank is no dummy). Finally, Frank buys it back from Sue for—you guessed it—$90 (Sue is no dummy, either). At this point, who comes out ahead?
Hospital Staff (Doctors, Nurses)
A staff member of a small hospital said, “The hospital staff consists of 16 doctors and nurses, including me. The following facts apply to the staff members; whether you include me or not does not make any difference.”
The staff consists of:
- more nurses than doctors;
- more male doctors than male nurses;
- more male nurses than female nurses;
- at least one female doctor.
Give the sex and job of the speaker.
Ton of Pennies
Ten pennies weigh an ounce. How much money is a ton of pennies?
Cube With 6 Cuts
A cube is made from a block of white pine, 6 cm on each edge. It is painted a nice barn red. After the paint dries, the cube is cut into 27 little cubes, each one 2 cm on each edge. This can be done with six cuts of the saw, right? Now, a question: Starting over, after making a saw cut, you are allowed to rearrange the pieces any way you want before making the next cut. Following this rule, can you make the 27 little cubes in fewer than six cuts of the saw?
Cube Frame, Vertices Numbered
Each of the lettered open cubes is a different view of the same original cube. Enter the missing corner numbers in each of the diagrams A through E.
