M starts cycling 64 meters straight from her office. During her journey she took 16 right turns. Finally she is facing towards west direction. In which direction she started cycling? (she took no left turn)
Show answer & explanation
Correct answer: B
Explanation
Each turn to the right corresponds to 90°.
Turning to the right 16 times:
16 × 90° = 1440°
Now,
1440° ÷ 360° = 4
She completed 4 full rotations; therefore, there was no change in her direction.
Thus, the initial direction = the final direction.
In the end, she is facing West.
