Twelve students stand in a circle facing the centre and representing the hours of a clock with the first student at the 1st hour position, second student at the 2nd hour position and so on. In which direction is the student on the right hand of the 10th student with respect to him?

Let's analyze the positions on the circular clock layout facing inside towards the center:
1. The $10^{\text{th}}$ student is standing at the 10 o'clock position (which is in the North-West quadrant relative to the center).
2. Since the student faces the center of the clock, their left hand points towards 11 o'clock, and their right hand points towards 9 o'clock along the perimeter.
3. Therefore, the student standing on the right-hand side of the $10^{\text{th}}$ student is at the 9 o'clock position.
4. Relative to the position of the $10^{\text{th}}$ student (treating 10 o'clock as the local origin), the 9 o'clock position lies in a South-West direction.
