One morning after sunrise, Sumesh and Ratheesh were standing on a lawn with their backs towards each other. Sumesh's shadow fell exactly towards his left hand side. Which direction was Ratheesh facing?

South

As, sun rises from east and sets in the west, we will consider the side of sun as east and then mark the rest of the directions accordingly. Thus, after making the chart we will wind that Ratheesh is facing the south direction.
