Direction sense — Mohan's facing after a rectangular path Mohan starts at point A, walks 1 km South, turns left and walks 1 km, turns left again and walks 1 km. Now he is facing which direction?

Introduction / Context:A two left-turn walk typically reorients the traveller 180° from the original heading.

Given Data / Assumptions:

• Legs: 1 km South → left to East 1 km → left to North 1 km.
• Each left turn is 90°.

Concept / Approach:Track heading after each turn, not just displacement.

Step-by-Step Solution:Start facing South.First left → face East.Second left → face North.Final step is towards North; hence final facing is North.

Verification / Alternative check:Sketching reveals a U-shaped path returning to a line parallel to the start, facing North.

Why Other Options Are Wrong:East/West/South-west do not match the heading after the second left.

Common Pitfalls:Confusing the direction back to A with current facing.

Final Answer:North
