Manohar starts his morning walk facing North. During his walk, he makes the following successive turns:
1. Turns $90^{\circ }$ to his right,
2. Turns $90^{\circ }$ to his right again,
3. Turns $180^{\circ }$ to his left,
4. Turns $180^{\circ }$ to his right.

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

Let's trace Manohar's orientation phase by phase using standard angles where North is $0^{\circ }$:
1. Initial position: Facing North ($0^{\circ }$).
2. **First turn ($90^{\circ }$ to his right):** Clockwise rotation of $90^{\circ }$. New direction = East ($90^{\circ }$).
3. **Second turn ($90^{\circ }$ to his right again):** Clockwise rotation of $90^{\circ }$. New direction = South ($180^{\circ }$).
4. **Third turn ($180^{\circ }$ to his left):** Counter-clockwise rotation of $180^{\circ }$. New direction = North ($0^{\circ }$).
5. **Fourth turn ($180^{\circ }$ to his right):** Clockwise rotation of $180^{\circ }$. New direction = South ($180^{\circ }$).

After all the turns, Manohar is facing South.
