Marks: +1, -0

Aman is facing north-west. He turns

90^{\circ}

in the clockwise direction and the n

135^{\circ}

anti clockwise, then where he is facing now?

East
West
North
South

Solution:

Concept:

Use directional angles to track rotations.

Explanation:

Let North be

0^\circ

. Then North-West is

315^\circ

(or

-45^\circ

).

Clockwise

90^\circ

:

315^\circ + 90^\circ = 405^\circ \equiv 45^\circ

(North-East).

Anti-clockwise

135^\circ

:

45^\circ - 135^\circ = -90^\circ \equiv 270^\circ

(West).

Thus, Aman now faces West.

Answer:

West
