Four pairs of lords and ladies all went to a royal ball. Each lord was wearing one color (yellow, red, blue, or green) and each lady was also wearing one of these colors. No couple was wearing the same color, so it was hard to tell who was married to who.
Using the clues, can you determine which lord is with which lady?
1. The Green Lord is with the Red Lady, if and only if the Yellow Lord is with the Blue Lady.
2. The Yellow Lord is with the Red Lady if and only if the Green Lord is with the Yellow Lady
3. The Red Lord is with the Blue Lady, if and only if the Green Lord is with the Red Lady.
Believe the solution is:
Red Lord with Blue Lady only if Green Lord with Red Lady
Left are: Yellow and Blue Lords and Yellow and Green Ladies - since yellow can't go together then
Yellow Lord with Green Lady
Blue Lord with Yellow Lady
