Tassador's is the elegant and most likely correct solution.

A considerably less elegant one is that the fireman was using someones eyeballs for poker chips.

While we're at it can someone help me with this puzzle?

Of three men, one man always tells the truth, one always tells lies, and one answers yes or no randomly. Each man knows which man is who. You may ask three yes/no question to determine who is who. If you ask the same question to more than one person you must count it as question used for each person whom you ask. What three questions should you ask?

and this.

A duck is in a circular pond with a menacing cat outside. The cat runs four times as fast as the duck can swim, but cannot enter the water. Can the duck get to the perimeter of the pond without the cat being on top of him?

Ouch my head,

1.- i have hard time to sort out the random one, but my brain is

2.- I am pretty sure it involve integral calcualtion, ouch i did any since 18 year ago arrrrrg

Edit: For 2 the duck need to be in the center right? you didnt specify but i guess it is.

Edit2: And what is the acceleration/deceleration rate of both?

 

[stratego]

For 2 the duck need to be in the center right? you didnt specify but i guess it is.

Lets assume yes, otherwise we can assume the cat is initially a minimal physical distance from the duck.

 

[Mrogreturns]

Edit- nevermind- silly question.

 

[Ultraworld]

I thought that the answer fot the first puzzle/picture was:
"six people eacdh take one egg" wich doesn't mean they take them out of the basket

 

[Perfection]

For number 2, perhaps they know the names of the others.

I believe the first cannot be determined

Yeah the duck flies!

It can- I have seen it before. But I wont give it away.

 

[SuperBeaverInc.]

Tassadar is correct, the others were woman. For the other two, I don't have any idea.

 

[Eastern Knight]

next one?

Of three men, one man always tells the truth, one always tells lies, and one answers yes or no depending on the answers of the other two, with A XOR B, where A and B are the two. Do a Google search if you don't know what XOR means.... It's safe to say I now have a sollution for the problem which will work 5 times out of 6...



And one more puzzle:

Say we have a string 40,000 km long, enough to encompass the Earth at it's Equator. We will consider that the Equator is exactly 40,000 km long, and that the Earth is totally smooth, so that the rope is tied very tight; so tight will it be that you will not even be able to run a needle under the rope. Now say you add 1 meter to the rope's length. We also presume that the rope is now held equally tight in the air, just as it was when it was shorter. Can you now put your hand under the rope? Can a dog walk under it? Can a skinny person crawl under it?

 

[Akka]

About the fireman one : it can be either that all the others are women.
But it can be also the Bobgote's solution.
Read the sentence. It say :
"they find
- a carpenter,
- a lorry driver,
- a car mechanic,
- and a fireman playing cards.
As you can see, you can either consider that find all the four playing cards, or find each one, and one playing card. There is several ways to play cards alone

No matter what the original perimeter was, if you increase the perimeter by 1 meter, the diameter will increase by 1/3.14 m, so the radius will increase by half of that, about 16 cm. You can easily put your hand under that, but it would have to be a very small dog to get under it.

 

[Pirate]

hmm, I actually did the math and came up with 16cm. I guess the riddle was to realize it was intuitive.

And I can't figure out the questioner one. That random guy throws a wrench in the whole thing. So how about this one:

You have 7 coins that look identical, but one is a counterfiet that wieghs slightly less - unnoticable to touch, but a balance scale will tell the difference. Can you figure out which is the counterfiet by using the scale only twice?

 

[col]

Weigh three against three. If they balance the odd one is counterfeit.

If they dont take the light side - it contains the counterfeit.
Weigh one against one. If they balance, the other one is counterfeit.
If they dont the light one is counterfeit.

(you can do up to 9 in 2 weighings )

 

[Perfection]

All right here's a stumper, made this one up meself!

Fred and Ed both are kings of perfectly spherical planets, their planets are in the exact same perfectly circular orbit around a star, (they are colinear with the star) additionally the period of rotation is exactly the same. Fred says a year is 361 days, Ed says a year is 359. They both are correct, how?

They rotate in opposite directions. Say that new years begins at "noon" when the star is directly above the king's head. Each day they progress 1 degree around the orbit so they have to rotate 361 or 359 degrees to bring the star back to directly overhead with each day, depending on if they rotate in the direction of the revolution or opposite the direction of revolution. Over the course of the year, these add up to one day more or less.

<edit> Good one, by the way!

 

[Perfection]

Yep, Good job! Here's another...

Fred and Ed have a brother Red.

Red has his own world.

Whenever you walk in a cardinal direction you go in a perfect circle and end up right back where you started.

On the surface of Red's world is 6 cities, each city has 5 Perfectly straight (relative to the surface) roads coming out of it, these five roads connect it to the other cities, these roads never cross.

What's so odd about Red's world?

Well, if you want to be creative, then go ahead and use that answer. But it is not the original answer.
