Question

A man is facing North-West. He turns ${90}^o$ in clockwise direction and then ${135}^o$ in the anticlockwise direction. Which direction is he facing now ?

• A. East
• B. West
• C. North
• D. South

Answer 1

Answer: (B)

West

Take clockwise as ${}^{\prime }{+}^{\prime }$ and anticlockwise as ${}^{\prime }{-}^{\prime }$
$\therefore$ $+{90}^o-{135}^o=-{45}^o$
As person is facing North west. Now, rotate that person 45 anticlockwise. Now, he is facing west direction.
Hence, option 'B' is correct.
