### Logic Game Q (Linear, Fixed)

I am trying to find the quickest way to solve this question. This is a take on Question 11, Section 1 of PT 11 (Game 2). Inferences have been made based on the original Q and rules...

Rules:
5 days, 3 variables ( F I J )
F>J
Variables can only be used max twice
Variables cannot be used consecutively XX

Question: What must be true?

There is 1 F
There are 2 Fs
There is 1 I
There are 2 Is
There is 1 J

(F/I)_ _ _ (I/J)

I've already made an inference from the original Question to knock out 2 of the variables and get it down to 3, but I am trying to figure out how others would approach this. I would prefer to not have to make any hypos.

Does every F have to come before every J or does the first F have to come before a J? If its the former, then there must be two F's I think. I didn't sketch though a only looked for like 30 seconds. About to go back and look.

All Fs must be before all Js

My answer isnt right anyway. could go FJIJI.

its two I's but I don't think theres any way you could just figure that out by looking at it unless you were quick thinking, though due to the rules (cant have F after J) then that would be a clue to start trying the hypotheticals that use I.

Should be D (two Is):

FIFJI
FJIJI
FIJIJ
FIFIJ

IFIFJ

etc...

Notice that F must be first or second since at least one F MUST be used.

### Re: Logic Game Q (Linear, Fixed)

zonto, your last comment makes me think I should set the diagram up more like this

(F/I) _ (I/J)

that would make it certain that F is in position 1 or 2 and make it more visible that there MUST be 2 Is. It would be a matter of thinking that there MUST be at least 1 F and 1 J, which would force them into positions 1 or 2, or 4 or 5 respectively.

Nick, I think you are diagramming the crap out of this game and it isn't quite necessary. Think about it like this:

Immediately when reading the rules, you will notice that two variables must be used twice in this game (2-2-1=5 spaces with 3 variables; 2x max/var. plus no consecutives). It's crucial to pick up on this because it reveals how restricted your answer choices are.

So, you have three options: double F and J, F and I, or I and J.

Following from that, you will notice that the first rule must be broken if F and J are doubled (FJFJI, IFJFJ, FIJFJ, etc). This means that, in order to solve the game, you must double F and I or I and J. Either way, I must be doubled.

### Re: Logic Game Q (Linear, Fixed)

i would jump to b and d in this problem. fills it with doubles.

F-I-F-J-J <<<wouldn't work under that rule and flipping the J-F would go against the other rule of F needing to be in front of J.

F-I-J-I-J

hope that kind helps

visually it would take me 15-20 seconds longer but since its a logic game, why not just write it down? takes like 5 seconds..
