The worlds first riddle!

1. all of them
2. numbers, 12 cents
3. (m)other and a boy
4. 2.1 lbs
5. 2*sqrt(10)
6. Cindy seeks psychologists.
7. Cindy cooks chicken.
8. 20 hours

[size=7]1) All of them 12 months have 28 days
2) House Nunbers-12 cents
3) 2b+g>F & 2g+b<M
the 2b+2g>F+g and 2b+2g<M+b
so F+g<M+b, so Mom and a boy beat Dad and a girl
4) 1 2/2 c=1 1/2# so 1c=1#
5) for the circumference to be entirely on black chessboard square it is on a single square. d=2"
6) Nancy Knows Pneumonia.
7) Greg Generates Gnus.
8) f=61*t s=58*t 61*t-58*t=3*t=60 so t=20--20 hours
9) 2350=2^3*3^2*5*7 and is a composite of the smallest prime numbers. As such it is an anti-prime. It has more factors than any smaller number. This behavior makes it a 'versatile' number
10) My old dogs? [/size]

I thank markr for the idea of answer camouflage.

Sorry guys! but I don't think that the circle has to be entirely on a single black square. The circumference can be shared by 4 black squares without there being any circumference on white squares. A white square would be in the center of the circle, but the circumf. itself lies on black at all times.
So......the diameter of the largest circle that can be drawn on the board in such a way that the circle's circumference is entirely on black squares is the square root of 2....or better known as the irrational #!
The diameter is:

...And these are only the first 1000 decimal points!

One could argue that there isn't any black at four points in the circumference then. But if you can argue that, you can argue that there is no white either. As long as the corners of the black squares touch...then the circumference lies on black. and the circumf. is then 1.4142....etc

I miscalculated.....the irational # is the radius. The diameter is twice that value.....which is still a very long number...

Hmmm. I didn't constrain my circle to one black square.
2*sqrt(10) > 2*sqrt(2)

sorry...didn't read your invisi-type right....my bad!!!

circle radius ib the shessboard is sqrt(1^2+3^2)

dia is 2*10^(1/2)

Rap

Not as nice as hidden text elsewhere, but it serves the purpose.

No problem. Does your horse race puzzle friend have any more puzzles?

I know one about 12 coins..one of them being a fake and you have three goes on the balance scale to figure which is the fake. But it's not really up to par with you guys's riddles! You've probably done it before...but if not...there you go. (The scale is the old fashioned type...like in the zodiac...so no actual weight values are given). Also, you don't know if the fake weighs more or less.

That's a good one, but I did it years ago.

i've just finished

thanks.

I have translated the secret ?'zip' code embedded in your reply, and whilst I appreciate your proposal of marriage, I fear I must decline at this present time.


May I offer my congratulations to both Mark and Rap for their contribution in improving the answers to the last 10 riddles.
The original answers are as follows:


1. All twelve months have 28 days. Some have more as well.

2. Prices quoted were for house numbers at 12 cents per number. A number'6' cost me 12 cents.

3. The mother and boy. Pitting the 2 winning teams against the 2 losing teams (boy + boy + girl + mother versus father + boy + girl + girl) will obviously result in a win for boy + boy + girl + Mother over father + boy + girl + girl. Take a girl and boy away from each side, and boy + mother must still beat father + girl. PHEW!!!!

4. 2.1 pounds. The 'whole crab' must weigh 0.6 pounds, and the 'half crab' 0.9 pounds, totaling 1 1/2 pounds. If the former were halved and the latter doubled, the weights would then be 0.3 and 1.8 pounds, totaling 2.1 pounds.

5. The diameter is 6.324 inches. Diameter is equal to twice the radius.

6. Pneumonic gnomes knew mnemonic names.

7. Ptomaine poisons Pnom-Penh's psychedelic philosophers.

8. The faster watch gains on the slower one at the rate of three minutes
every hour. After 20 hours, the faster one will be ahead by one hour.

9.2520 is the lowest number into which all the digits from 1 to 10 will divide.

10. Manhattan



In an effort to find something you guys do not know, I offer for your contemplation:

5. How can you make a pearl out of a pear

6. What is at the head of fashion, but always out of date

The pain continues: Part II

11. Is it safe to write a letter on an empty stomach

12. Can you explain how long cows should be milked

13. What is the best thing to put into cakes

14. What kind of umbrella do most people carry on a rainy day

15. What always happens at the end of a dry spell

16. When a child stomps through a mud puddle, what is the first thing he does

17. Why was Washington buried at Mt. Vernon

18. Where are kings usually crowned

19. What runs all around the yard without moving

20. What is all over the house



TWO COIN FLIPS
I flip a penny and a dime and hide the result from you, one of the coins came up heads.

What is the chance that the other coin also came up heads

[size=7]11. no - you'd have to penetrate you skin and abdominal muscles
12. the same as short cows
13. your teeth
14. open
15. precipitation
16. lift his foot
18. on the head
19. fence
20. roof

COIN FLIPS
1/3[/size]

11. ?
12. ?
13. Marijuana!!!!......Uhhmm, I mean Candles!!
14. The Morning Paper
15. You get laid, or…It rains (It depends on your definition of "a dry spell")
16. ?
17. ????
18. On the head
19. Fence….going on the "freeway" rational so no credit here!
20. Shingles….same as above

Lastly…..the trick question! Answer is 50% …. Being that you uncovered one of the coins already!
It would be a 25% chance that both turned "heads" before you told us the outcome of one of them! I'm also foreign and don't know if both a dime and penny have a "head" side. But lets assume they both do.
