Show answer & explanation
Correct answer: B
1. Start Point: Let the starting point be 'A'.
2. First Movement: Shyam walks 20 metres towards South to reach point 'B'.
3. Second Movement: Turning left (towards East), he walks 15 metres to reach point 'C'.
4. Third Movement: Turning left again (now facing North), he walks 20 metres to reach point 'D'. At this point, he is exactly parallel to his starting point line because the northward distance (20m) matches his initial southward distance (20m).
5. Fourth Movement: Turning to his right (towards East), he walks another 10 metres to reach the final point 'E'.
6. Distance Calculation:
Distance from starting point line 'A' to 'D' is equal to BC = 15 metres. Total horizontal distance from A to final point E = AD + DE = 15 metres + 10 metres = 25 metres.
7. Direction Calculation:
Looking from the starting point A, the final point E lies directly towards the East. Hence, the final position is 25 Metres, East.
