The coins cannot overlap each other. 4. The coins cannot hang off the edge of the table at all. 5. The first man to run out of room to place a coin on the table loses.

Riddle: A king decided to let a prisoner try to escape the prison with his life. The king placed 2 marbles in a jar was glued to a table. One of the marbles was supposed to be black, and one was supposed to be blue. If the prisoner could pick the blue marble, he would escape the prison with his life. If he picked the black marble, he would be executed. However, the king was very mean, and he wickedly placed 2 black marbles in the jars and no blue marbles. The prisoner witnessed the king only putting 2 black marbles in the jars. If the jar was not see-through and glued to the table and the prisoner was mute so he could not say anything, how did he escape with his life?

The Question: How many people have guessed three fruits correctly, and how many people have guessed four fruits correctly?

Riddle: Ray Whitcombe was found dead in his office at his desk. The police have narrowed the suspects down to three people: Mrs. Barbara Whitcombe, Ray's wife; Mr. Jason McCubbins, Ray's business partner; and Mr. Harold Nichols, Ray's best friend. All three visited Mr. Whitcombe on the day of his murder, and they explained the reason for their visit to the police. The police found Mr. Whitcombe with his wristwatch still on his right arm, a torn-up picture of his wife lying on the floor beside the trash can, and an ink pen in his right hand. On the desk, the police found a nameplate, a telephone that was off the hook, and a personal calendar turned to the July 5th page with 7B91011 written on it. After examining this evidence, the police knew their suspect. Who was it?

Show Answer ▼

Answer: Jason McCubbins, Ray's business partner. The calendar is the clue to solving this murder. The police realized that since Mr. Whitcombe was wearing his watch on his right arm, he must be left-handed. But the pen was found in his right hand. Realizing that the number on the calendar was written in a hurry and with his opposite hand, the police matched the written number with the months of the year. So the B was an 8, thereby giving us 7-8-9-10-11: July, August, September, October, and November. Use the first letter of each month and it spells J-A-S-O-N

Riddle: Walking home one day, you take a short cut along the train tracks. The tracks cross a narrow bridge over a deep gorge. At the point you are 3/8 of the way across the bridge, you hear the train whistle somewhere behind you. You charge across the bridge, and jump off the track as the train is about to run you down. As it happens, if you had gone the other way, you would have reached safety just before being run over as well. If you can run ten miles per hour, how fast is the train moving?

Show Answer ▼

Answer: The train is moving at 40 miles per hour. Imagine that a friend is walking with you. When the train whistle blows, you head away from the train, he heads toward it. When he reaches safety, you will be 6/8 (or 3/4)of the way across the bridge, and the train will have just reached the bridge. For the train to cross 4/4 of the bridge in the time you cross the remaining 1/4, the train must be moving four times your speed
