A boy walks 4 km east, 3 km south, 4 km west. Where is he from start? MCQ with Answer and Explanation

Explanation:
West (270°) -> SE (135°) means 135° shift? Actually 270° to 135° is -135° or +225°. If -135° (ACW) shift, then north (0°) -135° = -135° = 225° (South-west). So South-west.

Explanation:
South +180° right = north, +90° right = east? Wait: 180° right from south (180°) = 360°=0° North. Then right 90° = 90° East. So East. I miscalculated: North +90° right = East. So answer East. Option C.

Explanation:
East 4, north 3, west 4 -> east-west cancel, 3 km north. Distance = 3 km.
