Explanation

• Ramu's final position is calculated to be 60 meters East and 80 meters North of his starting point (house).
• To return to his house from this final position, he must travel in the exact opposite direction.
• The opposite of moving North is moving South, and the opposite of moving East is moving West.
• Therefore, the required direction to travel from his final location back to his house is South-West.

Why Other Options Were Wrong

• Option A: North-East is the direction from Ramu's house to his final position, not the direction of his return journey.
• Option C: Moving South-East would take him further away from his house, as he is already North and East of it.
• Option D: Moving North-West would also take him further away from his house, specifically further North.

Related Visual

• Visual 1: Diagram - A diagram tracing Ramu's path on a coordinate plane. Start at (0,0), move right to (90,0), then down to (90,-20), then left to (60,-20), and finally up to (60,80). An arrow pointing from the final point (60,80) back to the origin (0,0) clearly illustrates the South-West direction.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Direction Sense and Spatial Reasoning as background academic context rather than a clinical decision trigger.
• While not a direct clinical skill, direction-sense questions assess logical reasoning and spatial awareness. These are foundational cognitive abilities for nurses in tasks like navigating a large hospital, giving directions to patients' families, or understanding anatomical directions (e.g., proximal, distal).
• What if? If Ramu's final turn was a left turn instead of a right, he would have moved 100 m South from his position at (60, -20). His final position would be (60, -120). To return home from there, he would need to travel North-West.

How to Approach the Question

• First, visualize or draw a simple diagram with the four cardinal directions (North, East, South, West).
• Treat the starting point (the house) as the origin (0,0) on a coordinate plane.
• Track the position changes for each movement. East/West movements affect the x-coordinate (East is positive, West is negative), and North/South movements affect the y-coordinate (North is positive, South is negative).
• Calculate the net displacement from the origin to find the final position (e.g., x meters East/West, y meters North/South).
• The question asks for the direction to return home. This will be the exact opposite of the final position's direction relative to the start. For example, if the final position is North-East of the start, the return direction is South-West.
