Katie has a birthday party. She has invited 5 friends (Julie, Suzie, Yasmin, David, Richard) and their spouses (Drew, Barry, Conner, Sally, James) to her party. Each friend brings a gift (music box, scarf, necklace, perfume, handbag) and dessert (apple pie, chocolate cake, muffins, cupcakes, cookies) and they all arrive at different time (7:00, 7:15, 7:30, 7:45, 8:00). So try to find the spouses, the gifts, the desserts, and the arrival time of each friend.

1. The five friends are: Julie, the one who arrives last, the one who brings the muffins, the one whose husband is Barry, and the one who brings the perfume.
2. Neither David nor Richard arrives first, but one of them arrives last.
3. Yasmin doesn't like eating or cooking fruit.
4. James (who shares his initial with his wife) is the husband who arrives first.
5. Katie's female friends are the ones who bring the necklace, the music box, and the handbag.
6. Julie's husband is a musician so he likes gifts about music.
7. Neither Suzie nor Julie is a fan of chocolate.
8. The guest who arrives second either brings the handbag or brings the chocolate cake.
9. Neither Conner's wife nor Yasmin brings the cupcakes.
10. Sally, whose husband neither likes perfumes nor cupcakes, is famous for her delicious cookies.
11. David and his wife arrive 30 minutes later than the guest who brings the muffins.
12. The guest who brings the cupcakes is the one who arrives after the guest who brings the necklace.

First comment. Might I suggest telling people that Drew is female.
Dec 12, 2010

I liked the teaser, it had a fun story line. I do agree that there may be some confusion with drew being a girl.
Dec 12, 2010

Thank you I'm glad you liked it. I offered to add this information as a hint, I hope it can help the others.
Dec 27, 2010

I came up with a totally different solution but can't see where it's wrong. Can anyone point out the error?
Julie, James, music box, apple pie, 70
Suzie, Connor, handbag, muffins, 7:15
Yasmin, Barry, necklace, chocolate cake, 7:30
Drew, Richard, perfume, cupcakes, 7:45
Sally, David, scarf, cookies, 80

Sorry. Just reread my comment. I had Suzie and Yasmin's times reversed. Suzie was 7:30 and Yasmin was 7:15. That's necessary to make David arrive 30 minutes later.
Dec 31, 2010

Arrrrrgh! Yay, finally figured it out. Took three tries to finally solve.

Re: Drew being female - when you match up the male spouses, with female friends, Drew has to be female.

I still don't see why this solution won't also work:

Julie, James, music box, apple pie, 70
Suzie, Connor, handbag, muffins, 7:30
Yasmin, Barry, necklace, chocolate cake, 7:15
Drew, Richard, perfume, cupcakes, 7:45
Sally, David, scarf, cookies, 80

The clues for getting the arrival times of Suzie, Yazmine, David and Richard are missing.....

Clue #8 states "The guest who arrives second either brings the handbag(Suzie) or brings the chocolate cake (Yasmine)." But there is no clue for when either lady may have arrived so I just decided to have Suzie arrive at 7:15.

Getting the arrival time correct for David and Richard is dependent on which lady got there at either 7:15 or 7:30 Because of clue #11 which states "David and his wife arrive 30 minutes later than the guest who brings the muffins."

I agree with mama.... there are two solutions to this.
Feb 01, 2011

There is only one unique solution, the solution given by mamachew doesn't satisfy clue 12 - the cupcakes must arrive right after the necklace. The only way to do that is to have David with Drew at 7:45.

Thanks for posting this. I really enjoyed it - great job!
Feb 03, 2011

Thank you I'm glad you liked it...

Actually, clue #12 does not include the phrase "right after." It just says "after" which makes the timing piece very ambiguous. 7:45 is AFTER 7:15, so I think there are two solutions because the wording is open to interpretation. This still is a very nice puzzle--lots of excellent clues that make you think.
Mar 04, 2011

yay! i got this!! great teaser. though i didnt find it confusing, i do think the phrase "after" should be changed to "right after".
Apr 06, 2011

Good teaser, lots of fun. The fact that Drew is a female was easy to discern without the hint based on the obvious genders of the other five guests. The were 3 who definitely male, 2 who you know are female. That means that Drew had to be female. That shouldn't have needed to be pointed out.
May 14, 2011

This was an excellent challenge. I got it right on the first try but took at least 2 hrs to solve.
May 17, 2011

Very challenginging puzzle! I thought your clues were sufficient to determine who was male and female and when each arrived. Good job!
Dec 27, 2011

Awesome! I like figuring out who came first and last.
Jun 28, 2013

@mamachew; clue 12 states "...THE ONE who arrived after...". That implies "immediately after", not "sometime after".
Oct 06, 2013

Enjoyable, but I found the need to assume that Richard was heterosexual disappointing. Logic grids shouldn't require assumptions.
Sep 24, 2015

Ahhhhhh, Drew. It should be obvious that drew is a woman just from context, but when gender specifics matter unisex names are aggravating. Good puzzle otherwise
Jan 27, 2016

Great puzzle! Can I suggest that you state these are all heterosexual couples? Maybe it's just me but I did not assume these were all straight couples; I kept the possibility open that some of the marriages might be between two gay persons.
