Direction sense — Suresh's final position relative to start Suresh walks 7 km East, turns left and walks 4 km, turns right and walks 5 km, then turns right and walks 4 km. In which direction is he now from his starting point?

Introduction / Context:This tests relative direction from the origin after multiple orthogonal moves.

Given Data / Assumptions:Moves: +7 East → +4 North → +5 East → −4 North.

Concept / Approach:Compute net displacement components (x, y) from the starting point.

Step-by-Step Solution:East total = 7 + 5 = 12.North total = 4 − 4 = 0.Net vector = (12, 0), i.e., due East of the origin.

Verification / Alternative check:Plotting on grid shows the final point lies on the same east–west line as the start, to its East.

Why Other Options Are Wrong:North/South would require nonzero y; West contradicts the positive x result.

Common Pitfalls:Forgetting that consecutive opposite vertical legs cancel.

Final Answer:East
