Question

What part of a revolution have you turned through if you stand facing south and turn clockwise to face east?

• A. Three out of four parts.
• B. Two out of four parts.
• C. Three out of five parts.
• D. One out of two parts.

Answer 1

The correct option is A Three out of four parts.

Three out of four parts.
In order to face towards the east after turning clockwise from facing towards the south, one must turn $\frac{3}{4}$th of a full revolution. A full revolution, in this case, will be four ${90}^{\circ }$ rotations in the clockwise direction.
