Oct 2004, 4th Game (Parking Spots, $10, $12, $15)

[Question]

Under the time constraints of the exam, did anyone produce a really good diagram for this game?  I made the inference regarding potential prices, and potential distribution, but my overall diagram was pretty vague.  Y went 4th, and 3 had to cost more than 5.  I could've made templates but there seemed to be too many possibilities.

I don't think that a diagram is that useful for this game, actually.  It's more a matter of understanding what the conditions mean.

For 19., for example, $15 lot cannot be Friday, because then Wednesday wouldn't be more than Friday.

For 21., again, Z cannot be Friday, as X > Z.

It seems like there're a lot more questions like these in the more recent games, where diagrams are not necessarily very useful.

Y didnt have to go fourth.

[qqq]

Yes to cas.  In fact, if you look at Q. 20, X goes fourth in this case as X > Z so X = $15 and the $15 lot is the Thursday lot.

Diagrams might be useful for 20. and 22., but no very useful for the rest.

Y didnt have to go fourth.

Yeah, I know, X could've...  I'm going from memory here.

This is what I was hoping to hear.
