Today in class we started logic puzzles.
We did one called five boys and five dogs. There was a situation given and then 6 clues given to help narrow down the answers.
Clues:
1) No dog's name begins with the same letter as that of his master.
2) Rover is not Bart's or Sidney's dog.
3) Spot's master and the owner of the spaniel both have names beginning with the same letter.
4) Neither Eric's dog nor Bernard's dogs is the basset, nor is Snoopy.
5) Bart's dog and the collie are not called Spot or Snoopy.
6) Ralph's dog is not a terrior

Going through these steps, some are obvious and other you have to logically think to cross other options out. Obvious ones are such as 1, 2, and 6. The others you have to think if Spots master and the owner of the spaniel..., that means that Spots master cannot own a spaniel. First go through the list and cross out the obvious and then go through a couple more times gainning more infomation as you cross more out.
Answers: Eric had a collie named Rover, Bernard had a terrior named Spot, Bart's dog was a spaniel named Fido, Sideny's dog was a basset named Bowser, Ralph's dog was a poodle named Snoopy.
