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

E) None of these

Correct Answer: B

Solution :

Explanation Option (b) is correct. As shown in Figure, the man initially faces towards east i.e., in the direction OA. On moving 100° clockwise, he faces in the direction OB. On further moving 145° clockwise, he faces in the direction OC. Clearly, OC makes an angle of (145° - 100°) i.e., 45° with OA and as such points in the direction North - east.
