Concept:Direction sense problems are solved by tracking each movement step by step and comparing the final position with the starting point.
Explanation:Let the starting point be the origin
(0,0).
Mayank walks
35 m north, so his position becomes
(0,35).
Then he walks
45 m west, so his position becomes
(−45,35).
He is now facing west. A left turn from west means he now faces south.
Walking
35 m south brings him to
(−45,0).
Now he is facing south. Another left turn means he now faces east.
Walking
55 m east changes his position to
(−45+55,0)=(10,0).
So Mayank is
10 m away from the starting point, in the east direction.
Answer:Option D:
10 m, East.
