Harpreet faces north. She turns $135^\circ$ clockwise and then $270^\circ$ anticlockwise. Which direction is she facing now?

Explanation

1. 01

   Take clockwise as positive: net turn $= 135^\circ - 270^\circ = -135^\circ$, that is $135^\circ$ anticlockwise.

2. 02

   Anticlockwise from north: north-west $(45^\circ)$, west $(90^\circ)$, south-west $(135^\circ)$.

3. 03

   She faces south-west.
