Railway station is 5 km east from house. Post office is 5 km south of railway station then the location of post office from home?

Appeared in: AIIMS Delhi NO - 2018

Explanation

The problem involves a sequence of movements: first 5 km East, then 5 km South.
If the House is considered the origin (0,0), moving 5 km East places the Railway Station at (5,0).
From the Railway Station (5,0), moving 5 km South places the Post Office at (5,-5).
A location with a positive horizontal (East) and negative vertical (South) displacement from the origin is in the South-East direction.

Option A: South West is incorrect because the first movement is East (positive direction), not West (negative direction).
Option C: North East is incorrect because the second movement is South (negative direction), not North (positive direction).
Option D: North West is incorrect because the movements are East (positive) and South (negative), not West (negative) and North (positive).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Directional and Spatial Reasoning as background academic context rather than a clinical decision trigger.
While not a clinical question, spatial reasoning is a critical skill for nurses. It is essential for navigating complex hospital layouts, quickly locating emergency equipment, and efficiently moving between patient rooms.
This skill is also fundamental for emergency preparedness, such as understanding evacuation routes and patient triage locations within a facility.
What if? If the post office was 5 km north of the railway station, the final coordinates would be (5, 5), and the correct direction from the house would be North-East.

How to Approach the Question

Identify the starting point (House) and treat it as the origin.
Break down the problem into individual movements and their corresponding directions (East, South).
Visualize the path by drawing a simple diagram or using a mental coordinate system.
Plot the first movement: 5 km East from the origin.
From the new position, plot the second movement: 5 km South.
Determine the final position's direction relative to the original starting point.
