The Singapore Logic Puzzle
The Singapore Logic Puzzle (which is designed for 14 and 15 year olds in math competitions, not 5th graders as originally stated in some venues) reminds me a lot of the old GRE reasoning section. I loved that stuff.

Re: The Singapore Logic Puzzle
It looks a lot hairier than it actually is. I made things more obvious by dropping the dates into a spreadsheet so the cells lined up by month one way and date the other.
Apparently how one interprets Albert's first statement can make a difference in the outcome, too.

Re: The Singapore Logic Puzzle
But all Albert says is "We don't know." How the hells does Bernard respond to that with "Now I do"?????

Re: The Singapore Logic Puzzle
Don't look at it as a conversation, Yov, look at it as a logic statement.

Re: The Singapore Logic Puzzle
So take Albert's statement to
Mean that neither Albert nor Bernard know the birthday. Then you look at the options given.

Ooooooohhhhhhhh. I misunderstood the setup, I think I get it now!
Is this it?

Re: The Singapore Logic Puzzle
I went right to look for the solution, I could never do those kinds of puzzles. And even when I read the answer, I still didn't really get it. My brain isn't wired that way..

Re: The Singapore Logic Puzzle
Well, I applied the correct logic but did the date matrix wrong on the first try. So basically I solved it twice.
I am not great at these, but this one is not particularly difficult.

Re: The Singapore Logic Puzzle
I gave up and looked at the answer. My logic was roughly on the right track but got tripped up on a couple things.
I'm gonna disagree with Frelga and say that that was plenty tuff stuff.

Re: The Singapore Logic Puzzle
There are quite a few of these logic puzzles where the key to getting the correct answer is to draw conclusions from another person's ignorance. Here is another one.
Three wise men are told to stand in a straight line, one in front of the other. A hat is put on each of their heads. They are told that each of these hats was selected from a group of five hats: two black hats and three white hats. The first man, standing at the front of the line, can’t see either of the men behind him or their hats. The second man, in the middle, can see only the first man and his hat. The last man, at the rear, can see both other men and their hats.
None of the men can see the hat on his own head. They are asked to deduce its color. Some time goes by as the wise men ponder the puzzle in silence. Finally the first one, at the front of the line, makes an announcement: “My hat is white.”
He is correct. How did he come to this conclusion?

Re: The Singapore Logic Puzzle
I attached a jpg of my method with the spreadsheet.
Now to see if it works for hats.

That one was actually simpler--I didn't need the spreadsheet Re: The Singapore Logic Puzzle
What I love about the Singapore Logic Puzzle is all the pettiness and spiteful behavior and interpersonal drama.
What is with Cheryl, anyway? Why can't she just give a straight answer? Why does she have to give half the answer to one boy and half to another boy like she's sending out a coded WWII message? Is it part of some devious long con? Some sort of contest to see who gets to take her to the prom?
And why do Albert and Bernard hate each other so much? They could have cooperated from the beginning, but instead they jealously held their vital bit of birthday information back. And then the smugness, the taunting, the boasting!
Albert: I don't know it, but you don't know either! Ha ha ha!
Bernard: Suck it, Alturd, because even though I didn't know, now I do know, all because you opened your fool mouth! I glory in my superior knowledge!
Albert: Well I know it too now, Bernads, so you can suck it instead, and the glory is all mine!
And Cheryl just smirks at the two fools, because of course she was lying the whole time. Her birthday is October 14, and she's going to the prom with Darla. As if she would tell those petulant smug immature brats anything about her birthday!

Re: The Singapore Logic Puzzle
Faramond, dammit, just . . .
“There, peeping among the cloud-wrack above a dark tor high up in the mountains, Sam saw a white star twinkle for a while. The beauty of it smote his heart, as he looked up out of the forsaken land, and hope returned to him. For like a shaft, clear and cold, the thought pierced him that in the end the Shadow was only a small and passing thing: there was light and high beauty for ever beyond its reach.”

Re: The Singapore Logic Puzzle
I was looking for a like button, and I'm not even on Facebook.
What I find curious about both this and the three-hat puzzles is that their solution is dependent on each of the solvers being assured that everyone else is making accurate deductions, rather than just standing there wondering when they can take the stupid hat off.
I came across this one on a Russian feed. Skipping the story about two wise men and an obnoxious ruler, it boils down to two numbers greater than 1 and less than 100. Wizard A is given the product of multiplication (x*y), wizard B the sum (x+y).
A: I don't know the numbers
B: I knew you wouldn't know
A: Then I know
B: Then I also know.
What did the ruler had for breakfast?
OK, no, what were the numbers?
Edited to fix the puzzle.
