Mr. PK was all set to go to the village of WonderLand to meet his friend. So, he packed his bags and left for the village at 5 in the morning. Upon traveling on a road for miles, he came across a point where the road diverged into two. He was confused on which road to take. He gazed around and he saw two owls sitting on a branch. He thought he could ask for directions for the village from the two owls. So he went to the tree. There he saw a sign which read,
“One owl always lies, and one is always truthful. They both fly away if you ask them more than 1 question.”Mr. PK was caught in the dilemma of what to ask? And from which owl to ask, since he only had one question. What should Mr. PK ask?
