New Riddles

I have another new riddle page for you this week, and a few other good items.

Here are a couple hard "logic riddles" to test your brainpower on. I particularly like the elegance of the first one.

The Problem Of The Brainwave CD Weights

You manufacture brain wave entrainment CDs for companies that sell self-improvement products. You are at the post office, with ten boxes of them ready to close up and ship out, but you have a problem. Nine of the boxes contain CDs that are designed to put the listener into an "alpha" or relaxing state, and one is full of Cds that are designed to put the user into a deeper "delta" state, for deep sleep. They look identical, and you forgot to label them.

There is one difference, however. You remember that the "alpha" Cds weigh 13 grams, and because different CD "blanks were used, the "delta" Cds weigh 15 grams. Unfortunately, you can't feel the difference in weight by lifting them.

The post office does have a scale. It costs one dollar each time you weigh something, though, and you want to keep your costs down. How do you use the scale as few times as possible to determine which are the "delta" CDs?

Weighing The Gold

You have 15 tiny gold bars and...

- A U.S. family will spend an average of $250,000 on each child from time of birth until he/she turns 18.

- Christopher Columbus never quite discovered America. He discovered many Carribean islands, however.

A man lives down a long road that gets worse as he gets closer to home. He drives the first half of the route at 40 miles-per-hour, and the second half at 20 miles-per-hour. What will his average speed be for the entire trip?

(The answer is at the bottom of the page)

You need energy to move your brain as much as your body. Try deep breathing, go out and get some fresh air, eat an orange, or swing your arms around. Find the energy boosters that work best for you, and are easily available - then get in the habit of using them when you need them.

What If You Could Ask Anyone For Help?

Have you ever noticed how sometimes you are at your most creative when you are interacting with another person? You and your friend or acquaintance feed off of each other's ideas and help each other clarify things. Well what about those times when you are alone, or you have no one you wish to share your ideas with? What can you do then to stimulate creative thought and to find elegant solutions to your problems? You could try talking to Albert Einstein.

Okay, you might want to talk to Andrew Carnegie or Lee Iacocca if your problem has to do with making a factory more productive. A question about love might be better addressed to the Dalai Lama. The point is to have a conversation in your head with a historical person or expert who can help with your particular problem. Why would you want to do this?

Your Imagination Needs Form To Function

Whether you realize it or not, you have a powerful imagination. What you may not have, however...

Riddle Answer: 26.66 miles-per-hour. For example, if the road is 120 miles, he will go the 1st 60 miles at 40 mph, in 1.5 hours, and the 2nd 60 miles at 20 mph, in 3 hours. 120 miles in a total of 4.5 hours is an average speed of 26.66 mph. Try any other length of road and the answer will be the same.
