Here is a puzzle very similar to Arch119's Knight and Knave puzzle. Illustration says all. Guess the question the traveler asked. (When I was a teacher in Nuwakot a long time ago, a Japanese volunteer teacher (I still remember his name, Kazunori Iwata from Nagasaki ) had brought this puzzle to us. I had managed to solve it ! पठ्ठो दिमाग जो थियो, अहिले त बुढो भएछ भन्या, त्यो arch119 को कनाईट र कनेभ पजल सुल्झाउन खोज्या, के के नपुग्या जस्तो लाग्ने के के । संभवत: केहि त्रुटी छ त्यसमा । )
