Neha is facing north-east. She turns 270° anticlockwise, then 135° clockwise, then 225° anticlockwise, and finally 90° clockwise. In which direction is she facing now?
Neha faces south-east. Using clockwise angles from north, north-east is 45°. The net turn is minus 270 plus 135 minus 225 plus 90, giving minus 270°. Then 45 minus 270 is minus 225°, equal to 135°, which is south-east.

- BSouth-west
- CWestCorrect
- DNorth-west
Explanation
North-east is 45° clockwise from north. Net turn = -270 + 135 - 225 + 90 = -270°. Final angle = 45 - 270 = -225°, which equals 135°, i.e. south-east. So the correct direction is south-east, not among the listed ones; recheck: -225 + 360 = 135 = south-east.
