Roshan is facing south. He turns \[135{}^\circ \] in the anticlockwise direction and then \[180{}^\circ \] in the clockwise direction. Which direction is he facing now?

A)  North -east       

B)  North-west     

C)  South-east                   

D)  South-west

Correct Answer: D

Solution :

  From the figure it is clear that Roshan initially faces in the direction OX. On moving \[{{135}^{o}}\]anticlockwise, he faces in the direction OY. Then on further moving \[{{180}^{o}}\] clockwise, he faces in the direction OZ i.e. South west. Therefore, Roshan is finally facing in South-West direction.
