- South-west
Show the answer and the worked solution
Correct answer: B. North-west
Worked solution
- North becoming east is a rotation of 90° clockwise.
- Rotating south-west by 90° clockwise gives north-west.
- (Check: south → west and west → north under the same rotation.)
Answer: North-west.
The idea
Work out the single rotation the mapping describes, then apply it to whatever direction is asked. Testing it on a second known pair confirms the angle.
Shortcut. Every direction moves one quarter clockwise, so shift each part: S → W and W → N turn south-west into north-west.
Common trap. "South-east" — rotating the wrong way (anticlockwise), which carries south-west to south-east.
