Facing after left and right turns on West–South path: Roopa walks 15 m West, turns left and walks 12 m (South), then turns right and continues. What direction is she now facing?

Introduction / Context:
We only need the final facing, not the exact endpoint.

Given Data / Assumptions:

• Start facing West.
• Left turn from West → South.
• Right turn from South → West.

Concept / Approach:
Apply relative turns to the current heading: West → (left) South → (right) West.

Step-by-Step Solution:

Verification / Alternative check:
Left then right about the same pivot puts you back to the original heading.

Why Other Options Are Wrong:
South/North/East would require different turn sequences.

Common Pitfalls:
Mistaking right-from-South as East (it is West from South → right is West).

Final Answer:
West
