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.

Yup.. i agree with Detti... in this condition it impossible for all statement true both side... but its false both side. Because there will be paradoks at rhs 1st statement and lhs 3rd statement and also at 2nd statement if both are true it make blue lords with blue ladies too..

so,we can say there statement are false and... we wil get the answer...
