Logic Grid puzzles come with a handy interactive grid that will help you solve the puzzle based on the given clues.Logic-Grid
Five foreign college students met each other in the United States while attending the same school. Their names are Chris, Hugo, Sam, Anna, and Jessica. Each one has been in the US for a different number of years, is from a different country, and is currently learning a different language than all the others. Can you figure out who's who?
1. The five college students are Anna, the Mexican, the boy who wants to learn Italian, the one who has been in the US for 3 years, and the Australian (who doesn't want to learn Swedish.)
2. Chris has not been in the US for the longest time, but the one learning Vietnamese has.
3. If Hugo is Russian, then Sam wants to learn German. Otherwise, Chris is Mexican and Jessica wants to learn Japanese.
4. Neither of the girls qualify to be an American citizen. To become an American citizen, you must have lived in the US for at least 5 years.
5. If Sam is Australian, then Hugo is learning Italian. If not, then Jessica is Russian and Chris is learning Vietnamese.
6. The Mexican is learning Swedish and the 3-year resident is learning Japanese.
7. The Frenchman has been in the states for 2 years.

Good Puzzle. However I fail to see the clue that differentiates between the country of origin of Anna and Jessica.
Nice teaser ... not too difficult. First I thought there were not enough clues, but it all fell into place going through the second time.
Roscoep -> look at clue 5. The first statement is the true one. In the second statement you can then eliminate Jessica NOT originating from Russia.

xsagril, thanks for the comment. I see your point. But the way I read it Jessica could be Russian and Chris could be learing some language other than Vietnamese. That would make the statement 2 false as well.
Roscoep, I can see how you interpreted the clue. I think the way it was written both parts were intented to be false. Clue 3 follows the same pattern.
Anyhow, just thought I'll give my 2 cents ..

thanks for the feedback people!
clues 3 and 5 have two groups w/ two parts each. If part of one sentence is true, the 2nd is too, but the whole other sentence isn't.
clue 2 automatically makes the first sentence in clue 5 true.
i'm not sure if that helped any, but if anyone has any more questions, just ask...

I liked this one. It made me think a little but it wasn't too hard. I understood that is the first part was true, the second was false, and I had no problems, but I can see how it could get confusing. Still, a job well done!!!
thank you!!!
I liked it. Thanks.
I wasn't sure if you were doing the tricky names-that-could-be-either-gender thing, with Chris and Sam. Luckily, it all fell into place with your clues regardless.

Very difficult for me but I enjoyed it
aw, thanks!
I thought it was pretty easy... of course I just finished one of the hardest ones I've ever done, so I guess I was just in logic puzzle mode.
it's one of my easier logic grids, actually, according to votes...
I enjoyed the teaser, but thought I'd make a suggestion about the form of clues 3 and 5. I assumed that you meant it to be either the first set of conditions existed and the second didn't, or the second set was true and the first wasn't. But they could also be construed as to allow individual items from the different parts of the sentences. For instance, in no. 3, If Hugo is Russian, then Sam necessarily wants to learn German. This could seem to allow that if Hugo is not Russian, Sam may still want to learn German. It doesn't explicitly exclude this possibility. I do think, however, that most would make the assumption which you intended. Good teaser!
thanks for the feedback, it WAS intended to be in sets
I must be looking too hard, but I can't see what differentiates Chris being here 5 years and Hugo 4.
I don't really remember what I wrote, but it was probably either an elimination clue or something that you had to use two clues together to solve...
I didn't finish it.
The If then clues confused me.
Great teaser though.

I loved this one! The "if-->then" clues add an extra level of logical difficulty that makes you think even harder -- great job!!
Great teaser! I had no problems with it. The "if...then" clues made it more fun.
That obviously didn't work out. I somehow got the exact opposite of everything. Good teaser though!
I LOVE the if-than clues! I've done a number of these LG's, and I've never seen it. I appreciate the connection between (true) Logic and LG's
Thanks, mocha!
I loved the if-thens, but I suppose I got lucky and made the proper assumption... reading other comments though, I can see how it could be taken another way.
Very fun - thanks!
