Mrs. Green, Mrs. Brown, and Mrs. Blue attended a Halloween
Party. They came wearing green, brown, and blue costumes but not
necessarily in their respective order. Mrs. Green said to the lady
wearing the brown costume, "Did you notice that the three of us are
wearing costumes having colors not corresponding to our names?"
Determine which colored costume each of them wore during the
Halloween Party.
Solution:
Since Mrs. Green talked with the lady wearing the brown costume,
Mrs. Green did not wear brown. We know that she did not wear green.
Therefore, she must be wearing a blue costume. This leaves the green
costume for Mrs. Brown, and the brown costume for Mrs. Blue.
