M starts cycling 16 meters straight from her office. During her journey she took 12 right turns. Finally she is facing towards east direction. In which direction she started cycling? (she took no left turn)
Show answer & explanation
Correct answer: D
Explanation
Each turn to the right corresponds to 90°.
Turning to the right 12 times:
12 × 90° = 1080°
1080° ÷ 360° = 3
This means she completed 3 full rotations; therefore, there was no change in direction.
Thus, the initial direction = the final direction.
In the end, she is facing East.
