Question

Ravi walks 10 m towards North, then turns right and walks 6 m. He again turns right and walks 10 m. In which direction is he from the starting point?

• A. North
• B. East
• C. West
• D. South

Hint:

If the vertical distances (North/South) are equal, the person ends up directly East or West of the start. If the horizontal distances (East/West) are equal, they end up North or South.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Direction sense problems are solved by tracking movement relative to the four cardinal directions: North (Up), South (Down), East (Right), and West (Left). A "right turn" depends on the direction the person is currently facing.

Step 2: Key Formula or Approach:
The best approach is to map the path step-by-step:
• Facing North: Right turn leads to East.
• Facing East: Right turn leads to South.
• Facing South: Right turn leads to West.
• Facing West: Right turn leads to North.

Step 3: Detailed Explanation:
1. Initial Position: Let the starting point be $O(0,0)$. 2. Move 1: Ravi walks 10 m North. He is now at point $A$, 10 m above the start. 3. Move 2: He turns right (now facing East) and walks 6 m. He is now at point $B$. 4. Move 3: He turns right again (now facing South) and walks 10 m. 5. Since he walked 10 m North and then 10 m South, he is back on the same horizontal level (latitude) as the starting point. 6. However, he is still 6 m to the right of the starting line.

Step 4: Final Answer:
Ravi is 6 m to the right of the starting point, which is the East direction.
