Question from UPSC Prelims 2024 CSAT
Explanation :
Initial Movement:
Direction: West
Action: Walks 100 meters West.
First Turn:
Turn: Left
From West, turning left means facing South.
Action: Walks 100 meters South.
Second Turn:
Turn: 225° clockwise from South
Understanding the Turn:
– Starting Direction: South (which is 180° on a compass)
– Clockwise Turn: Adding 225° to the current direction.
– Calculation: 180° (South) + 225° = 405°
– Since 405° is equivalent to 45° (405° – 360°), the final direction is 45°, which corresponds to North-East on a compass.
Final Direction: North-East, Answer: d) North-East
