Imran faces north. He turns 90° clockwise and moves, then turns 135° anticlockwise and moves, then turns 90° clockwise and moves, then turns 225° anticlockwise. Which direction is he facing at the end?
Imran finally faces south. Measuring clockwise from north, his heading goes 0°, 90°, -45°, 45° and finally -180°, which equals 180°. That direction is south.

Explanation
Clockwise angles from north: start 0°. +90 gives 90°. -135 gives -45° (315°, north-west). +90 gives 45° (north-east). -225 gives -180°, i.e. 180° (south). Check: 45-225 = -180 = 180°, which is south. So the answer is south.

One question tells you little. A timed set on Direction Tests shows your real accuracy, how long you take and where you lose marks.
