(a) It is clear from the figure, that the hour hand starts from 6 and turns through 1 right angle. Hence, it will be reach at 9. (b) It is clear from the figure, that the hour hand starts from 8 and turns through 2 right angles. Hence, it will be reach at 2. (c) It is clear from the figure, that the hour hand starts from 10 and turns through 3 right angles. Hence, it will be reach at 7.
