Where will the hour hand of a clock stop if it starts
(a) from 6 and turns through 1 right angle?
(b) from 8 and turns through 2 right angles?
(c) from 10 and turns through 3 right angles?
(d) from 7 and turns through 2 straight angles?

Solution:

We will be using the concepts of clockwise and Anticlockwise Rotation, right angle to solve this.

(a) Starting from 6 and turning through 1 right angle, the hour hand stops at 9. Refer to the below image.

(b) Starting from 8 and turning through 2 right angles, the hour hand stops at 2.

(c) Starting from 10 and turning through 3 right angles, the hour hand stops at 7.

(d) Starting from 7 and turning through 2 straight angles, the hour hand stops at 7.
