Yeah, actually I got the logic game about the different books. I drew a simple diagram and used short names for the books - reading the long names of objects during the test can really confuse me. Actually I thought that the long names were the most confusing part of this game - once I logically seperated them out it became fairly simple.
I cannot figure out the Green/Red truck game to save my life. It's the third game similar to this one I get totally stumped on - I don't know why. If someone can help me that would be awesome !!!
Here's the question (Questions 6-11)
In a single day, exactly seven trucks - S, T, U, W, X, Y, and Z - are the only arrivals at the warehouse. No truck arrives more than once that day. Each truck is either green or red (not both). The following conditions apply
- No two consecutive arrivals are red
- Y arrives at some time before both T and W
- Exactly two of the trucks that arrive before Y are red.
- S is the sixth arrival
- Z arrives at some time before U
6. Which one of the following could be the order, from first to last, in which the trucks arrive?
A) X, Z, U, Y, W, S, T
B) X, Y, Z, U, W, S, T
C) Z, W, U, T, Y, S, T
D) Z, U, T, Y, W, S, X
E) U, Z, Y, T, S, W, X
I figured out easily that it cannot be C, D, or E. However, I cannot figure out why it is A (correct) as opposed to B. The difference being is the location of Y. Incidentally, question 11 asks for which of pair cannot arrive consecutivelly, and it is Y and Z, which I don't understand either and it may be the reason why I cannot figure question 6. I guessed it properly as it was a 50-50 question, but that was luck.
Question 7 deals with which pair cannot be red - and it is T and S. I assume that's because they are always consecutive. However, in the Z X Y T U S W combination, I don't see any violations and T and S can both be RED. All the other trucks can be green. What is wrong with this combintation?
The way I understand it, the constraint with two trucks that arrive before Y are red means that there must be at least 3 trucks before Y (since two consecutive trucks cannot be red) and that all but 2 of the 7 trucks can be green...
I know I am missing something, and beside the obvious suggestion to my intelligence, can anyone point me in the right direction... ? Thanks
