I am facing East. I turn\[100{}^\circ \]in the clockwise direction and then\[145{}^\circ \]in the anti-clockwise direction. Which direction am I facing now?

A)  East                

B)  North-East

C)  North  

D)  South-West

Correct Answer: B

Solution :

As shown in the figure given here, than man initially faces towards East i.e. in the direction OA. On moving \[100{}^\circ \] clockwise, he faces in the direction OB. On further moving \[145{}^\circ \] anti-clockwise, he faces in the direction OC. Clearly, OC makes an angle of \[(145{}^\circ -100{}^\circ ),\] i.e. with OA and as such points in the direction North-East.
