Question

Bala walked 25 km towards west, took a left turn and walked 15 km. He again took a left turn and walked 30 km. He then took a right turn and stopped. Now he was facing which direction?

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

Hint:

Keep a fixed compass: from West, a left turn points South; from South, a left turn points East; from East, a right turn points South. Writing the sequence of facings avoids coordinate confusion.

Answer 1

The Correct Option is C

Step 1: Assign bearings: North \(=0°\), East \(=90°\), South \(=180°\), West \(=270°\); left \(=-90°\), right \(=+90°\).

Step 2: Starting bearing \(270°\) (West); after left, left, right: \(270-90-90+90=180°\).

Step 3: A bearing of \(180°\) is South.
\[ \boxed{\text{South}} \]
