Question

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-West
• E. None of these

Answer 1

The correct option is B North -East

As shown in the figure, the 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 ${145}^{\circ }$ anticlockwise, he is facing the direction OC. Clearly, OC makes an angle of $({145}^{\circ }-{100}^{\circ })$ i.e. ${45}^{\circ }$ with OA and so, the man faces the direction North-east.
