### Puzzle 1

Weighing marbles

Because this is a hard puzzle giving the solution just like that would be too easy. Therefor if you mail me the solution I will tell you if it's wrong or right. If you want the solution without solving the puzzle send me another logic puzzle (with solution) and I will send you the answer of this puzzle.

### Puzzle 2

The man with the hat

Nr.1 sees a white and a black hat in front of him. He cannot tell what hat he is wearing, so he keeps his mouth shut. If nr.1 saw two black hats, he would know that he was wearing a white hat. Because nr.1 does not say anything nr.2 knows that nr.1 must see a black and a white hat. Nr.2 sees a black hat and therefor he knows that he himself wears a white hat.

### Puzzle 3

### Puzzle 6

Don't hang yourself

6 meters 28 centimeters.
The outline of a circle is 2*PI*r. If you want a rope that is one meter above the ground rnew=r+1. So you need 2*PI*(r+1)-2*PI*r more rope.
So,
x=2*PI*(r+1)-2*PI*r
x=2*PI*r+2*PI-2*PI*r
x=2*PI
x=6.28
It does not matter what the radius of the circle is. You always need 2*pi more rope.

### Puzzle 7

### Puzzle 8

What a rip-off

1 sheep - 1 dog = 1 goat + 1 dog
1 sheep - 1 goat = 2 dogs
A sheep is 10 dinars, but what costs a goat?
The money they received for their camels is a square. And the decade of this square is odd (total money / 10 dinars), because they could not divide the sheep equally.
Now the interesting thing is that all squares with an odd decade ends on a 6. (162 = 256, 242 = 576). So a goat costs always 6 dinars.
10 - 6 = 2 dogs
So a dog costs 2 dinars.
