Show answer & explanation
Correct answer: C
Correct direction: South-East
Reason: The given change maps South-East to North and South to North-East, which is a rotation of 135° clockwise. Apply the same rotation to West to find its new direction.
Represent common directions as angles: North = 0°, North-East = 45°, East = 90°, South-East = 135°, South = 180°, South-West = 225°, West = 270°, North-West = 315°.
Check the given mapping: South-East (135°) → North (0°). That is a rotation of 135° clockwise (135° → 0°).
Apply this rotation to West (270°): 270° - 135° = 135°, which corresponds to South-East.
Therefore, West becomes South-East under the specified change.
