Rahul walks 12 m north, 5 m west, 12 m south. How far is he from start? MCQ with Answer and Explanation

Explanation:
South +90° right = west, -90° left = south again.

Explanation:
South 10, left (east) 5, left (north) 10 -> net east 5 km.

Explanation:
Tracing backward: if a 45° right turn put him facing North-East, he must have been facing North prior to the turn. That means his left turn put him facing North, implying he initially walked East. Since all movements were East and North, his final position is deeply in the North-East quadrant. Given the options, standard typo resolution points to the primary initial direction vector context, aligning closest with East (or unlisted NE).
