Hari walked 40 meters towards the east. Then he turns right and walks 20 meters, then he turns right and walks 18 meters. He again turns right and walks 10 meters. After this, he turns left and walks 24 meters more. Finally, he turns right and walks 12 meters. In which direction is Hari facing now?

Appeared in: Haryana CHO - 2022

Explanation

The question asks for the final direction Hari is facing, which depends only on the sequence of turns, not the distance traveled.
Starting direction is East.
First turn is right, changing direction from East to South.
Second turn is right, changing direction from South to West.
Third turn is right, changing direction from West to North.
Fourth turn is left, changing direction from North to West.

Option B: Hari faces South only after his first right turn from the starting East direction. Subsequent turns change his direction away from South.
Option C: East is the initial direction Hari was facing before making any turns. He never faces East again after his first turn.
Option D: Hari faces West after his second right turn and again after his left turn. However, his final action is another right turn, which changes his direction from West to North.

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.
This question type is not directly related to clinical nursing but assesses logical reasoning and problem-solving skills.
Strong analytical skills are crucial for nurses in interpreting patient data, prioritizing care, and making sound clinical judgments under pressure.
What if the last turn was a left turn instead of a right turn? If the final turn was left from the West-facing direction, Hari would have ended up facing South.

How to Approach the Question

Identify the starting direction mentioned in the problem. Here, it is East.
Draw or visualize the cardinal directions (North, East, South, West) as a reference.
Sequentially process each turn. Remember that a 'right turn' is a 90° clockwise rotation and a 'left turn' is a 90° counter-clockwise rotation.
Ignore the distances walked, as they are only relevant for determining the final position, not the final direction.
Track the facing direction after each turn until you reach the end of the sequence.
The direction after the last described turn is the final answer.
