Answers: (In real life, these are very improbable to the point of impossibility, mind you.)

A rope broke, a bell rang, a man fell to his death. What happened?

A blind man was walking along the edge of a cliff, gauging his distance from the edge using the sound of buoy's bell. The rope anchoring the buoy broke and it floated further out to sea. So the blind man thought the edge was further than it actually was- he fell off the cliff to his death.

Near Chicago's O'Hare Airport, a man is frozen and dead in the middle of a park. What happened?

He stowed away in the landing gear compartment. He froze to death while the plane was in flight (there's no heating in there!). When the pilot extended the landing gear, he fell out.

Very nice, alpha!

Heres another one:

A couple was playing a game of tennis, when suddenly the ball rolled away and down a very improbably shaped hole. When the man went to get it, he found that this hole is very deep, and had an awkward bend in it, so he couldn't reach down and grab it. Further more, the ground around the hole was made of clay, so he couldn't dig it out with a shovel. Yet this man was very resourceful, and was able to use a common 5 letter object to get the ball out. What was it?

Humph, another correct answer. Ok, heres one that I just solved, its pretty hard:

For students took a test. The answers were always either A or B. The teacher scored three of them, but forgot to score the Colin's! Right before he goes to ask the teacher about his score, one of the other students calls to him and says that he can figure out his score based on the other three's score and answers.

Mary's answers were:

Code: Select all

1 2 3 4 5 6 7 8 9 10
B B A B A B B A B B

Dan's:

Code: Select all

1 2 3 4 5 6 7 8 9 10
B A A A B A B A A A

Lisa:

Code: Select all

1 2 3 4 5 6 7 8 9 10
B A A A B B B A B A

And Colin:

Code: Select all

1 2 3 4 5 6 7 8 9 10
B B A A A B B A A A

If Mary got a 70, Dan got a 50, and Lisa got a 30, then what did Colin get?
Each answer was worth 10 points to make 100 points total.

Explanation to come but just the answer now:

60%

Explanation (Click to Show Hidden Text)

How I did it was to formulate a probable answer key by looking at the results.
On  4 questions they all answer the same, so I assumed they would all be correct. Except that the 3rd person only got 30%, so this led me to formulate 4 different answer keys, where in each one, a different one of those 4 questions they all got wrong instead of right. Now, that means that the last person already has 30%, so that person has to be wrong on all of their other answers. Meaning the other 6 answers on each of the 4 answer keys is the opposite of person 3's answer:
1.
1 2 3 4 5 6 7 8 9 10
A B A B A A B A A B
2.
1 2 3 4 5 6 7 8 9 10
B B B B A A B A A B
3.
1 2 3 4 5 6 7 8 9 10
B B A B A A A A A B
4.
1 2 3 4 5 6 7 8 9 10
B B A B A A B B A B

Score collin's test with this, and you get 6 correct answers 4 wrong answers->60%

I also checked the answers by brute forcing it with a computer program, plug it into a java editor if you want to run it
(yes its rather messy and likely redundant, be nice gh and gh-like people)

Code: Select all

public class TestPercents {

    public static void main(String[] args) {
		int[] answerKey = new int[10];
		
		for (int d1 = 0; d1 < 2; d1++){
			for (int d2 = 0; d2 < 2; d2++){
				for (int d3 = 0; d3 < 2; d3++){
					for (int d4 = 0; d4 < 2; d4++){			
						for (int d5 = 0; d5 < 2; d5++){
							
		for (int d6 = 0; d6 < 2; d6++){
			for (int d7 = 0; d7 < 2; d7++){
				for (int d8 = 0; d8 < 2; d8++){
					for (int d9 = 0; d9 < 2; d9++){
						for (int d10 = 0; d10 < 2; d10++){
							answerKey[0] = d1;
							answerKey[1] = d2;
							answerKey[2] = d3;
							answerKey[3] = d4;
							answerKey[4] = d5;
							answerKey[5] = d6;
							answerKey[6] = d7;
							answerKey[7] = d8;
							answerKey[8] = d9;
							answerKey[9] = d10;
							if (checkAnswer(answerKey)){
								System.out.println(answerKey[0] + "," +	answerKey[1] + "," + answerKey[2] + "," + answerKey[3] + "," + answerKey[4] + "," + answerKey[5] + "," + answerKey[6] + "," + answerKey[7] + "," + answerKey[8] + "," + answerKey[9]);

    }

I'm starting to run out of riddles! But no matter, this one is the hardest yet...

There is a loop of numbers, as follows:
37 --> 58 --> ? --> 145 --> 42 --> 20 --> 4 --> 16 --> Loop back to beginning

What number goes in the blank?
