Difficulty: Medium
Correct Answer: South east
Explanation:
Introduction / Context:This is a composition of diagonal moves (NW, SW, SE, NE) on a square grid with equal step lengths (200 m). We compare Roy’s final coordinates to Babu’s coordinates.
Given Data / Assumptions:
Concept / Approach:Compute coordinates relative to Rahim, then subtract to get Roy relative to Babu.
Step-by-Step Solution:
Babu = (−1, +1).Joseph = (−1, −1).Gopal = (−1, −1) + (+1, −1) = (0, −2).Roy = (0, −2) + (+1, +1) = (1, −1).Roy − Babu = (1 − (−1), −1 − 1) = (2, −2) ⇒ South-East.Verification / Alternative check:Diagramming a 2×2 diamond centered near Rahim shows Roy diagonally opposite Babu along the SE diagonal.
Why Other Options Are Wrong:
Common Pitfalls:Mixing “relative to Rahim” with “relative to Babu.” Always subtract the reference point’s coordinates.
Final Answer:South east
