A boy runs 4 km to east side then turn right side and run 6 km, and then again turn left and run 8 km, then again turn left to run 3 km and finally again turn left to run 4 km. Now the boy is looking in which direction and the distance of final point from the starting point is :

West, $\sqrt{73}$

He is = \(\sqrt {8^2 + 3^2}\)  = \(\sqrt {73}\) From the starting point.

The correct answer is option (1) : West, $\sqrt{73}$
