Given information:
Barry walked 4 km in a particular direction, then turned left and walked another 4 km. He then started walking directly towards the starting point.
Solution:
Step 1: Initial Direction
- Barry first walks 4 km in one direction before turning left.
- After turning left, he walks another 4 km.
- This means he has moved in a square pattern, ending up back where he started.
Step 2: Determining Initial Direction
- If Barry is currently moving in a South-West direction, and he started by moving 4 km in one direction and then turned left, his initial direction must have been to the East.
- This is because turning left from East would lead him to the North, which aligns with his current South-West direction.
Therefore, Barry initially started walking in the East direction.

Let the starting point be A and his initial direction of movement be North. Then his movement may be depicted as shown:
So, final assumed direction of Barry is South-East. But according to the question his final direction is South-West, i.e. 90o towards the clockwise direction wrt the assumed final direction. Hence, his actual initial direction must also be 90o towards the clockwise direction wrt the assumed initial direction. So, his actual initial direction is towards the East.
