Ramya starts facing East. She then performs the following turns in sequence:
1. Turns $90^{\circ }$ clockwise.
2. Followed by a $180^{\circ }$ anticlockwise turn.
3. Makes a complete about-turn ($180^{\circ }$).
4. Finally, turns $90^{\circ }$ clockwise.

After completing all these turns, which direction is she facing?

Let's keep track of the orientations step-by-step from the initial direction (East):
* Initial Position: Facing East.
* Step 1: Turns $90^{\circ }$ clockwise $⟹$ Now facing South.
* Step 2: Turns $180^{\circ }$ anticlockwise $⟹$ Opposite of South is North.
* Step 3: Makes a complete about-turn ($180^{\circ }$) $⟹$ Opposite of North is South.
* Step 4: Turns $90^{\circ }$ clockwise $⟹$ Turning $90^{\circ }$ clockwise from South points to West.

Thus, she is facing West at the end.
