Answer 2

Answer:

A man is standing facing the Southeast direction. He takes 145 turns each of 45º in the clockwise direction and finally a 90º turn in the anti-clockwise direction. He is facing the (a) East direction.

Explanation:

• A man is given to be standing in the South east direction. If we consider the direction x and y axes to be the hands of a clock, the man is standing at twenty two and a half minutes.
• If he takes 145 turns, each of 45 degrees, we have $(8*18)=144$, therefore, after 18 turns of 45 degrees each, he will be back to his same position. After 145 turns, he will therefore be at South position.
• Taking a 90º turn anti-clockwise, he will land at the East position.

Hence, a man is standing facing the Southeast direction. He takes 145 turns each of 45º in the clockwise direction and finally a 90º turn in the anti-clockwise direction. He is facing the (a) East direction.
