Tom started walking keeping his back toward the Sun. After walking for few meters, he turned left, and then turned right. In which direction, is he walking now?

West or east

In order to answer the question, one should know that the sun rises from the east and sets in the west. So, in the morning his back will be towards the east side and in the evening his back will be towards the west side.

So, the answer comes out to be either east or west.
