July 1998 Riddle

It's all in the balance...
Which weighs more: a pound of feathers or a pound of gold? (source: ananomous from AOL.com)

Answer: A pound of feathers weighs the same as a pound of gold. A pound is a pound, is a pound, is a pound regardless if it is a pound of feathers or a pound of gold. [Note: some people got a bit technical on us. They pointed out that gold, silver, and precious stones are measured in Troy Weight. Troy Weight is a system of weights based on a pound containing 5,760 grains, in which 24 grains = 1 pennyweight, 20 pennyweights = 1 ounce, and 12 ounces = 1 pound. Well, how about that...go figure that!]

Answer: Zero crows are left. The crows all flew away when they heard the farmer shooting his gun.

Puzzle Two: In a hardware store, you ask the price of an item on display. Practically every hardware store carries this item, for no home should be without it. The following conversation takes place.
Speakers What they say... What they mean...
Clerk: The price is a quarter each. The price of each house "number" cost 25¢.
Customer: That means seventy five cents for 100. The house number "100" takes 3 numbers, one "one" and 2 "zeros"; each number cost 25¢ for a total of 75¢ for 3 numbers.
Clerk: That's right. If you buy 3 numbers, it will cost 75¢.
Customer: Well, I'll take fifty seven. The house number 57 takes 2 numbers, a "five" and a "seven".
Clerk: That will be fifty cents. 2 numbers at 25¢ each costs 50¢.

The conversation makes perfect sense. What is the item?
(source: Pat Alvarado, California)

Answer: They are discussing the price of "house numbers".

One Solution

A Canadian visitor to the FolkArt & Craft Exchange, Latchesar Stoyanov (Latch to his friends) found 92 possible answers to the 8 Queen puzzle. We asked Latch how he found the 92 anwers:

How I found 92 answers. Yesterday I saw your new riddle and I liked it so much that I could not do anything else.

First I develop an algorithm and try by hand, but this took to long, because of that I wrote a small program which stops after finding one answer. When I analyzed the first answer I was able to find another 3 symmetrical.

Now I was curious to know how many answers exist. So I modify the program not to stop. I was surprised to find 92 answers! They are NOT all symmetrical!

The source-code is in C and was compiled with Borland C++.

There are 4 men who wish to cross a river using a bridge. The bridge supports only two people at a time. You need a torch to cross the bridge. The torch has to be carried by the people crossing the bridge. It cannot be thrown or rolled over from one side to the other. The 4 men must cross over the bridge in a total of 17 minutes.

You have 8 marbles. Out of the 8 marbles there is one marble that weighs slightly heavier than the rest. The rest of the marbles all weigh the same. How would you find the heaviest marble when you can only weigh them two times using a liberty scale?
(submitted by Chay Day Kao, Bothell, Washington)

Answer:
Step 1: Select any 6 marbles. Place 3 marbles on each side of the scale. If one side goes down, go to Step 3. If they balance go to Step 2.
Step 2: Place the two remaining marbles on the scale. The marble that goes down is the heavy marble.
Step 3: Using the 3 marbles that went down in Step 1, select any 2 marbles. Place one marble on each side. If one side goes down, that is the heavy marble. If they balance the other marble is the heavy marble.

No 3:
You need to time nine minutes. All you have is a 4 minutes hourglass and a 7 minute hour glass. How do you do it? (
submitted by Andrew O'Brien, Beaverton, Oregon)

Answer: This puzzle may be solved in several ways. But they are all variations of this solution.
Step 1: Start the 4 minute and the 7 minute hour glass.
Step 2: When the 4 minute runs out, Start them both again. At this point the 7 minute will have 3 minutes to go.
Step 3: When the 7 minute runs out, start them both again. At this point the 4 minute will have 1 minute to go. Now we will begin timing for the nine minutes.
Step 4: When the 4 minute runs out, one minute has expired. Turn the 4 minute over twice for the remaining 8 minutes for a total of 9 minutes.

June Brain Teaser:

There are three words in the English language that end with "gry." One is "angry" and one of them is "hungry." What is the third word?

Everyone uses it every day, and everyone knows what it stands for. If you have been listening, I have already told you what the word is. (submitted by Lori Baranoski, Bensalem, Pennsylvania)

Answer: Frankly we do not know the answer to this Brain Teaser. Many people submitted solutions or guesses. Here is a summary of the responses submitted by various readers.

Solution #1 We looked up the word "gry" in the Webster's New Universal Unabridged Dictionary, Deluxe Second Edition, page 807. Here is the definition in that dictionary:

gry, n. [L. gry, a trifle; Gr. gry, a grunt] 1. a measure equal to one-tenth of a line. [Obs.] 2. anything very small. [Rare]

Frankly I am disappointed in the answer and I feel the riddle is misleading in the way it is worded. The riddle stated: "Everyone uses it every day, and everyone knows what it stands for. If you have been listening, I have already told you what the word is."

How often have you used 'gry'? I never have used it and did not know what it stood for. Furthermore, the reference to 'If you have been listening, I have already told you what the word is' is too vague and how I've been 'told' eludes me.

Lori, this was your riddle. Do you think there may be another word ending in 'gry' that complies more fully with the spirit of the riddle? Gry, gry, gry (grunt, grunt, grunt...).

Solution #2 It has been suggested the answer to this puzzle is "energy." The rationale is that the riddle doesn't specify that the letters g-r-y need to appear in that order. If this is the case, then obviously, there are more than three words in the English language which satisfy this rule. However, the restriction that everyone uses 'it' everyday, leaves much to interpretation.

Consider the word 'clergy.' While some may not consult their clergy everyday, it does satisfy the order independent rule. Likewise, some may engage in a daily 'orgy', but this is a matter of definition. (I would hate to think that members of the clergy participate in this.) Some other words which appear with the letters g-r-y in no particular order are: allergy, lethargy, liturgy, metallurgy, and synergy.

I would have to conclude that this riddle remains unsolved, since there are more than three words which qualify under this interpretation.

Solution #3 Some said the answer was "it". Part of the riddle states: "Everyone uses it every day, and everyone knows what it stands for."

The problem with "it" as the answer is that it completely ignores the g-r-y criteria. Again if "it" is the answer we're very disappointed.

Solution #4 "What do you mean there's no answer to the June Brainteaser???? I can't believe you would publish a brainteaser without knowing the answer. I won't waste my time reading your brainteasers in the future."

Solution #5 I read somewhere that the third word was 'antidisestablishmentarianismgry.' This was posted to a Usenet group somewhere, and I don't really trust it because I looked it up in Webster's Third New International Dictionary (yes, the big one) and it wasn't there. However, the people at Webster are notorious for screwing us out of every prefix and suffix. [Jeff]

Solution #6 This riddle, brain teaser went around here for about three weeks - we had it on the radio stations, and were asking friends and relatives all across Canada! The answer is agree or agry. Agry is a bead, agree is it's homonym, which is part of the puzzle. One of the clues is that the word or it's HOMONYM is used daily! I hope that the powers that be agree on this answer, or a whole lot of us will be in turmoil again, wouldn't you agree :) [Reba] The wording of the riddle made no mention of "homonyms". Our belief is that we need to continue the search.


May Brain Teaser:

In the basement there are 3 light switches in the "off position". Each switch controls 1 of 3 light bulbs on the floor above. You may move any of the switches but you may only go up stairs one time. How can you determine which switch controls each light bulb? (submitted by Gloria MacCormick, Cleveland, Ohio)

Answer: Turn any one switch to the "on" position for 5 minutes, then turn that switch "off". Quickly turn any other switch to the "on" position and run up stairs. Feel the two lights that are "off". One of them will be "hot" because is was "on" for 5 minutes. Obviously the "hot" bulb is controlled by the first switch you turned "on". The light that is currently "on" is controlled by the switch you last turn "on". The "cold" bulb that is "off" is controlled by the only switch left. When solving problems we often need to use all our senses.
