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

A)  East                            

B)  North-East      

C)  North                          

D)  South

Correct Answer: B

Solution :

: As shown in figure, I initially face towards East, in the direction OA. On moving 100\[{}^\circ \] clockwise, I face in the direction OB. On further moving 145\[{}^\circ \] anticlockwise, I face in the direction OC. Clearly, OC makes an angle of (145\[{}^\circ \] - 100\[{}^\circ \]) i.e., 45\[{}^\circ \] with OA and which is North-East.
