Priya is facing north-west. She turns 90° anticlockwise, then 225° clockwise, and then 45° anticlockwise. Which direction is she facing finally?
She faces north-east. North-west is 315°; subtract 90° to get 225°, add 225° to get 450° or 90°, then subtract 45° to get 45° from north, which is north-east.

Explanation
North-west is 315° from north. Anticlockwise 90° gives 225°. Clockwise 225° gives 450°, which is 90°. Anticlockwise 45° gives 45°, which is north-east. A common error is to add the anticlockwise turns, which gives a wrong result such as east.
Did you get it right without looking?
One question tells you little. A timed set on Direction Tests shows your real accuracy, how long you take and where you lose marks.
