R is moving towards south. After taking 9 right and 10 left turns in which direction he will be moving?
Show answer & explanation
Correct answer: B
Explanation
Right turns: 9 times
Left turns: 10 times
Turn = 10 – 9 = 1 left
Since the person was walking south, he now only needs to turn left once.
Turning left (90° counterclockwise) once from south gives us the east direction.
Conclusion
The person must now be walking east.
Therefore, the correct option is 2) east.
