## Trivia question #5:

Two people are standing back to back. They each walk away from each other for three feet. Then they both turn left and walk for another four feet, and then stop. Now, how many feet apart are they standing?

A. 10

B. 7

C. 25

D. 5

## Answer: A. 10

If you remember the a^{2 }+ b^{2} = c^{2 }rule from math class, that's what'll help you solve this problem. This rule states that if you have a triangle, the sum of the squares of the two shorter sides equals the square of the longest side. And in this problem, the walkers' paths form parts of triangles. You may want a pencil and paper to "draw out" this problem and visualize the triangles.

Draw two lines labeled "three feet" for the distance they walk away from each other. Then draw two lines labeled "four feet," going in opposite directions, for the distance they walked after their left turns. Now draw a line connecting the points at the ends of those lines (representing where the people are now). This line represents the distance you're trying to figure out.

Now, you've got two triangles touching at the corners. Two sides of each are 3 feet and 4 feet (the distances each person walked). The unknown sides represent two halves of the distance you're trying to find. So break out that Pythagorean Theorem: Three is a, 4 is b. 3^{2 }+ 4^{2} = 9 + 16 = 25 = c^{2}. Take the square root of 25 and you get 5, which is the longest side of these mini-triangles. Five feet is half of the distance between the people. Five times two is ten!

Here's another three-sided puzzler: Try to figure out how many triangles are in this image.

## Trivia question #6:

You're trapped in a room with two doors. Only one door will lead you out of the room safely, but you don't know which. A guard stands in front of each door. One guard always lies, the other always tells the truth, but you don't know which is which. You can only ask one guard one question. What question do you ask, and what do you do once the guard has answered?

A. "Which is the safe door?" Go through the door the guard tells you.

B. "Which is the safe door?" Go through the other door.

C. "If I were to ask the other guard which was the safe door, which door would s/he say?" Go through that door.

D. "If I were to ask the other guard which was the safe door, which door would s/he say?" Go through the other door.

## Answer: D. "If I were to ask the other guard which was the safe door, which door would s/he say?" Go through the other door.

If you chose the lying guard, the lying guard is telling you the door that the truthful guard would *not *say is safe. If you chose the truthful guard, the truthful guard is telling you the door that the lying guard *would *say is safe. Either way, the door the guard responds with is *not *the safe door. Go through the other door and you're out!

If you got that one right, you might be ready to try to solve 25 of the toughest riddles ever.

## Trivia question #9:

Lizzie, Isaac, Justine, and Mike each bought a different dessert. One of them bought a cupcake; one bought a doughnut; one bought a brownie; and one bought ice cream. One spent $1; one spent $2; one spent $3; and one spent $4. Using the set of clues below, who bought the ice cream?

- CLUE 1: Lizzie spent more money than Justine.
- CLUE 2: Justine bought the brownie.
- CLUE 3: Of the person who spent $1 and the person who spent $4, one of them was Lizzie and the other one bought the doughnut.
- CLUE 4: The person who bought the cupcake, the person who bought the brownie, the person who spent $2, and Isaac are all different people.

Who bought the ice cream?

A. Lizzie

B. Isaac

C. Justine

D. Mike

*[Source: Buzzfeed]*

## Answer: D. Mike

- We know (because of Clue 3) that Lizzie spent either $1 or $4. Because of Clue 1, we also know Lizzie spent more money than Justine, which means Lizzie can't have spent $1 (the lowest amount). So Lizzie spent $4. Because of Clue 3, this means that the person who did spend $1 bought the doughnut.
- Clue 2 says that Justine bought the brownie. Because of Clue 4, we then know that Justine didn't spend $2, since the $2-spender and the brownie-buyer are not the same person. We also know that Isaac didn't buy the cupcake (or the brownie)
*or*spend $2. - Therefore, since we already know Lizzie spent $4, Mike is the only one who could have spent $2.
- Since the $1-spender and the doughnut-buyer are the same person, this has to be Isaac—he's now the only one who doesn't have either dessert or money accounted for yet.
- That leaves Justine having spent $3.
- Clue 4 says that the person who spent $2 and the person who bought the cupcake are not the same. Since Mike spent the $2, Lizzie must have bought the cupcake.
- This leaves us with our answer: Mike bought the ice cream!

If you figured that out, reward yourself with your dessert of choice. Oh, and you might be ready to tackle this logic puzzle invented by Albert Einstein himself.

## Trivia question #11:

If you take away one letter, you're left with twelve. What is the word?

**(ANSWER TO BONUS QUESTION:** L**oui**siana)

If you can find the missing word in this logic puzzle, you might be a genius.

## Trivia question #12:

...whose first digit is one-fourth of the last digit; the second digit is six times the first digit; and the third digit is the second digit plus three.

## Answer: 1694

Since the second digit is six times the first, the second digit must be 6, because it's the only number that is still a single digit and is divisible by six. (It couldn't be 0 either, because the second digit is six times the first digit, which would make the first digit 0, impossible for a four-digit number.) Once you've figured that out, you can figure out that the first digit is 1, the last digit is 4, and the third digit is 9.
