Hello,
This is a question from an old logic game (analytical reasoning question, as I believe they're now called). I get one answer but the book gives another. I'm trying to reconcile my answer with their answer which is the correct one. Any ideas would be greatly appreciated! Thanks!
Question:
Seven piano students—T, U, V, W, X, Y, and Z—are to give a recital, and their instructor is deciding the order in which they will perform. Each student will play exactly one piece, a piano solo. In deciding the order of performance, the instructor must observe the following restrictions:
X cannot play first or second.
W cannot play until X has played.
Neither T nor Y can play seventh.
Either Y or Z must play immediately after W plays.
(Does this mean that I can pick which one I want to go after W? That is, I can pick Y or Z for after W, that what it seems to me, but maybe they BOTH have to go after W. What do you think?)
V must play either immediately after or immediately
before U plays.
Question 1
If V plays first, which one of the following must be true?
(A) T plays sixth.
(B) X plays third.
(C) Z plays seventh.
(D) T plays immediately after Y.
(E) W plays immediately after X.
My answer is (in order from 1-7 [right to left]):
V, U, X/T, T/X, W, Y, Z. (whereas: X/T = X or T in any order)
The booklet gives a similar answer but different three and four (X/T and T/X). They give:
V, U, T, X, W, Y, Z.
Thanks again!

Re: Analytical Reasoning Question
Is it possible that the book is just describing a potential arrangement, not the necessary arrangement? If I'm reading this right, this arrangement is possible and disproves all but the right answer, whereas your arrangement accounts for more possibilities but leads to the same answer.
Also, where is this from?

Re: Analytical Reasoning Question
Hello,
Yes, I suppose you're right. It's probably just telling me that this is just one possibility and not necessarily the ONLY option. Mine allows for more movement of the two letters.
I've gotten it from here:

See for yourself; maybe you'll be able to explain it a bit better for me.

Re: Analytical Reasoning Question
Thanks! You've confirmed what I thought. I was sure there were many other possibilities, but it only gave one, and therefore it me doubt.
Thanks a lot for your time!
