If South-East becomes North, what will North become?

Appeared in: AIIMS BHOPAL NO- 2018( Shift-2nd)

Explanation

The core logic is to identify the angle and direction of rotation from the given premise and apply it to the target direction.
The premise 'South-East becomes North' establishes a 135-degree counter-clockwise rotation (moving from 135° on the compass to 0°).
Applying this same 135-degree counter-clockwise rotation to the original 'North' (0°) position results in a new position at -135°, which is equivalent to 225°.
On a standard compass, the direction at 225° is South-West.

Option A: South-East is the starting direction in the premise. The new position of North cannot be the same as the original position of South-East.
Option C: North-East is at 45°. This would be the new position of South after a 135° counter-clockwise rotation (180° - 135° = 45°).
Option D: West is at 270°. This would be the new position of North-East after a 135° counter-clockwise rotation (45° - 135° = -90°, which is 270°).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Directional sense and logical reasoning as background academic context rather than a clinical decision trigger.
While not a clinical question, this type of logical reasoning is a foundational skill for nurses.
It enhances problem-solving abilities, which are crucial for interpreting patient data, prioritizing care, and making sound clinical judgments under pressure.
What if the rotation was 90 degrees clockwise? If South-East (135°) became South-West (225°), a 90° clockwise rotation, then North (0°) would become East (90°).

How to Approach the Question

First, visualize or draw a standard compass with the cardinal (N, S, E, W) and intercardinal (NE, SE, SW, NW) directions.
Identify the transformation given in the premise: 'South-East becomes North'.
Calculate the angle and direction of this rotation. Moving from SE (135°) to N (0°) is a 135° counter-clockwise turn.
Apply this exact same rotation (135° counter-clockwise) to the direction you are asked about, which is 'North'.
Calculate the new position of North: 0° - 135° = -135° or 225°.
Identify the direction that corresponds to the new angle (225° is South-West) to find the answer.
