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 angle?

(c) from 10 and turns through 3 right angle?

(d) from 7 and turns through 2 straight angle?

Answer:

We all know that in 12 hours hour-hand turns through 4 right angles. In a turn of 1 right angle, the hour hand moves 3 hours.

(a) Its hours hand stops at \[(6+3)i.e.,9\]

(b) Its hours hand stops at \[(8+2\times 3)i.e.,\,14\,\,i.e.,2\]

(c) Its hours hand stops at \[(10+3\times 3)i.e.,\,19\,\,i.e.,7\]

(d) Its hours hand stops at \[(7+4\times 3)i.e.,\,19\,\,i.e.,7\]
