If you really want me to. But I would have to erase human existence. I do not think I want to do that.

And I appologize for the riddle. Anileve posted her guess so I figured it was acceptable for me to do the same.

Ok, I was thinking about it all day at work and looking for some loophole in the problem; there is no possible way to solve it. The only thing I can assume is the wording of the problem. It states that the lines cannot intersect each other, but it doesn’t say that it cannot be a straight line. This is my attempt, if this is incorrect, Seap please explain the answer to the first problem. I think I am mentally drained. My solution is attached.

That gave me a good excuse to finally install and try out my PC Notetaker!. This thing is really sweet.

Here's your answer eve:

By the way, once again, if you think #1 or #2 cannot be done, try to prove it. If you try and try and you see that you can't do it, maybe it can't be done. So see if you can prove it.

Here's your answer eve:

No problem Seap jan, do you prefer Barry White or Tom Jones, white or red?

In terms of PC Notetaker, it is pretty cool as well as the price. In addition I simply don't see much use in it for myself.

Apparently I cannot attach any pictures, so I cannot present the solution to the problems.

Another riddle
===============

All for one coin

There once lived a wealthy merchant in Kashmir whose son was as lazy as he was foolish. No matter what the merchant said his son did the opposite. If, that is, he did anything at all. The merchant finally had all he could take. “I want you to go to the marketplace,” he told his son, “and buy something for us to eat, something for the cow to eat, and something for us to plant in the garden. And you may spend only this one small coin. If you can do it, come back home. If you can't don't come home.”

As the boy walked toward the marketplace, he began to cry. He could not think of any way to buy all those things with the coin his father had given him. He'd never be able to go home. He was crying so loudly a girl working in the field heard him and asked what's wrong. When he told her about his father's orders and all he had to buy with one small coin, the girl shook her head and told him not to worry (naturally women have a better knacks at solving problems ) She said he could easily do what his father wanted and told him how.

That night the boy went home with a smile on his face as well as something to eat, something to drink, something to feed the cow, and something to plant in the garden. His father was very surprised and very impressed. How did the boy do it? And let me just kill the obvious possibility, he didn't slaughter the girl.

Here is a more mathematical one.
==============

The sort of “Breakfast Problem” propounded by Metrodurus in 310AD.

Demochares has lived one-fourth of his life as a boy, one fifth as a youth, one third as a man, and has spent thirteen years in his dotage. How old is the gentleman?

Explain your answer please.

Yay, me like thread.

I got the same thing as Emil.

I tried to attach it for selective viewing, but I forgot that it doesn't accept .doc files.




(1/4)x + (1/5)x + (1/3)x + 13 = x

Solve for x.
