Whenever a person takes three right turns, the final direction is always opposite to the starting direction (if starting North, final is West).
Initial Movement
Rahul walks 20 m towards the North. He is currently facing North.
Tracking Turns
1st Right Turn: He faces East. 2nd Right Turn: He faces South. 3rd Right Turn: He faces West.
Final Direction Verification
After the final right turn from South, he is moving towards the West. Therefore, he is headed West.
A: East is incorrect because it is the direction after the first right turn. C: South is incorrect because it is the direction after the second right turn. D: North is the initial direction, which is not his final heading.
B is correct because following the sequence of three right turns (North to East, East to South, South to West) leads him to face the West direction.
Remember that four turns in the same direction (e.g., 4 right turns) always bring you back to your starting orientation.
