Sohan is facing towards north. He rotates by 145 degrees in clockwise direction. He again rotates by 290 degrees in anticlockwise direction. He again rotates by 345 degrees in anticlockwise direction. He finally rotates by 400 degrees in clockwise direction. In which direction is he facing now?

Correct option is D

According to question,
Net Rotation = Rotation in Anti-clockwise - Rotation in Clockwise
Net Rotation = (290 + 345) - (145 + 400) = 635 - 545
Net Rotation = 90o
