Given below are two statements:

Statement I : A person facing North, after turning 90° clockwise, faces East.
Statement II : After turning 90° anti-clockwise from North, the person faces East.

In the light of the above statements,choose the Correct answer from the options given below:

  • A.Both Statement I and Statement II are true.
  • B.Both Statement I and Statement II are false.
  • C.Statement I is true but Statement II is false.
  • D.Statement I is false but Statement II is true.

Answer: C

Statement I is true but Statement II is false.

Clockwise from North the directions run North, East, South, West. A 90° clockwise turn from North therefore faces East, so Statement I is true.

Anti-clockwise from North the order is North, West, South, East, so a 90° anti-clockwise turn faces West, not East. Statement II is false.

The options treating both as true miss that the two turns go in opposite senses and so must end in opposite directions.
