Q22

Is there a quick way to go through this type of question? It would just take forever to diagram every single possibility.

Thanks

Using previous work from the game will help eliminate answer choices. So if you encounter this question, skip it until you have more hypotheticals that may help you. That is, if you are totally not sure what the answer is.

_ _ _ _ R/S _

We know that if J4 ---> J is before S and T
We know that if ~J4 ---> J is after S and T

We also were told that the 2nd or 3rd slot is reserved for either K or R.

If J is 4th, we know that this will occur:

_ _ _ J S T

Three variables left are H-K, R

The only other possibility in the game is ~J4 and we have rule governing that.

_ _ _ _ R/S _

So in this scenario we know that S and T come before J. Lets consider where J can go if not 4th. We know it cannot go 1st or 2nd as we must place S and T before it. J could not be third either. As the 2nd and 3rd slots could not be filled with either K or R, rather slots 1-3 would be taken up by S/T T/S J.

J could not go fifth either, as this is reserved for R or S. So J must go sixth. In both scenarios, K is lower in cost than J.
