Four friends, Ali, Joy, Kay, and Lyn, decided to celebrate Kay’s birthday with dinner at the Clever Cafe. Each chose one main course (duck,
beef, pork, or fish) and one dessert (mousse, torte, fruit, or crepe) but
no two chose the same dish. Their surnames, in no particular order,
are Gorman, Foster, Fields, and Devlin. 
Use the following clues to determine their full names and what they had to eat.
1. Joy never eats pork but Ali had crepe.
2. The beef-eater has the letter ‘a’ in her first name.
3. Ms Gorman had fruit dessert but is not the birthday girl.
4. The fish-eater had torte but she wasn’t Ms Devlin.
5. Ms Foster had duck but not mousse.


Sagot :

We know:
1.Ali eats Crepe-she is not Gorman (because she eat fruit), she doesn't eat Fish (because The fish-eater had torte)
2.The beef-eater has the letter ‘a’ in her first name-Aly or Kay
3.Ms Gorman had fruit, and is not Kay =>It's Joy or Lyn
4.The fish-eater had torte -is not Devlin, but not Gorman (because she eat fruit) , and not Foster (because she eat duck)=>is Fields!
5. Ms Foster had duck but not mousse

=>We have:
Aly-Foster-duck-crepe;
Joy-Fields-Fish-torte;
Kay-Devlin-beef-mousse
Lyn-Gorman-pork-fruit.
