Answer
Correct Answer: East and South
Explanation
Introduction / Context:We need final facings for two independent walkers after identical turn patterns.
Given Data / Assumptions:
- Rani: West → left → South → left → East.
- Sarita: North → left → West → left → South.
Concept / Approach:Apply turns relative to each traveller's current heading.
Step-by-Step Solution:
Rani facing sequence: West → South → East (final East).Sarita facing sequence: North → West → South (final South).Verification / Alternative check:Two lefts rotate 180° from the original heading.
Why Other Options Are Wrong:They mismatch at least one traveller's final orientation.
Common Pitfalls:Assuming both end with the same facing; they start perpendicularly, so final facings differ.
Final Answer:East and South
