A person walks 100 m Westward, then turns left and walks 100 m. He then takes 225^0 turn clockwise. In which direction is he walking now?

Question

Accepted Answer

The correct answer is option D. Let's trace the person's direction:
1.  **Walks 100 m Westward**: The person is facing West.
2.  **Turns left**: If facing West, a left turn means turning 90 degrees counter-clockwise. This changes the direction to South. The person is now facing South.
3.  **Takes a 225-degree turn clockwise**: From facing South:
    - A 90-degree clockwise turn from South leads to West.
    - Another 90-degree clockwise turn from West leads to North. (Total 180 degrees clockwise).
    - Remaining turn: 225 - 180 = 45 degrees clockwise.
    - A 45-degree clockwise turn from North leads to North-East.

Alternatively, using degrees (North = 0°, East = 90°, South = 180°, West = 270°):
1.  Starts facing West (270°).
2.  Turns left (90° counter-clockwise): 270° - 90° = 180° (South).
3.  Takes a 225° turn clockwise: 180° + 225° = 405°.
4.  To find the final direction, subtract 360° (a full circle): 405° - 360° = 45°.
5.  45° corresponds to the North-East direction. This question tests direction sense and angular turns.
