7.  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?

(a) Starting from 6 and turns through 1 right angle the hour hand stops at 9. (b) Starting from 8 and turns through 2 right angle sthe hour hand stops at 2. (c) Starting from 10 and turns through 3 right angle the hour hand stops at 7. (d) Starting from 7 and turns through 2 straight angle the hour hand stops at 7.

6.  How many right angles do you make if you start facing

(a) south and turn clockwise to west?

(b) north and turn anti-clockwise to east?

(c) west and turn to west?

(d) south and turn to north?

The number of right angles we can make from the given conditions are- (a) 1. (b) 3. (c) 4. (d) 2.

5.  Find the number of right angles turned through by the hour hand of a clock when it goes from

(a) 3 to 6                                 (b) 2 to 8                          (c) 5 to 11

(d) 10 to 1                               (e) 12 to 9                        (f) 12 to 6

Number of right angles turned through by the hour hand of a clock when it goes from (a) 3 to 6,   (b) 2 to 8,   (c) 5 to 11,  (d) 10 to 1,   (e) 12 to 9,  (f) 12 to 6  are (a) 1. (b) 2. (c) 2. (d) 1. (e) 3. (f) 2.

4. What part of a revolution have you turned through if you stand facing

(a) east and turn clockwise to face north?

(b) south and turn clockwise to face east?

(c) west and turn clockwise to face east?

(a) If we are standing facing east and turn clockwise to face north we have turned through  of a revolution. (b)  If we are standing facing south and turn clockwise to face east we have turned through   of a revolution. (c) If we are standing facing west and turn clockwise to face east we have turned through half of a revolution.

3.  Which direction will you face if you start facing 

(a) east and make  \frac{1}{2}  of a revolution clockwise?

(b) east and make  1\frac{1}{2}   of a revolution clockwise?

(c) west and make  \frac{3}{4}  of a revolution anti-clockwise?

(d) south and make one full revolution?

(Should we specify clockwise or anti-clockwise for this last question? Why not?)

(a) West. (b) West. (c) North. (d) South. No need to specify clockwise or anti-clockwise for the last question as after one complete revolution we would be facing in the same direction.

2. Where will the hand of a clock stop if it

(a) starts at 12 and makes  \frac{1}{2}   of a revolution, clockwise?

(b) starts at 2 and makes  \frac{1}{2}   of a revolution, clockwise?

(c) starts at 5 and makes  \frac{1}{4}  of a revolution, clockwise?

(d) starts at 5 and makes  \frac{3}{4}   of a revolution, clockwise?

(a) The hand of a clock will stop at 6 after starting at 12 and making    of a revolution, clockwise. (b) The hand of a clock will stop at 8 after starting at 2 and making    of a revolution, clockwise. (c) The hand of a clock will stop at 8 after starting at 5 and making    of a revolution, clockwise. (d) The hand of a clock will stop at 2 after starting at 5 and making    of a revolution, clockwise. 

1. What fraction of a clockwise revolution does the hour hand of a clock turn through, when it goes from

(a) 3 to 9                       (b) 4 to 7                  (c) 7 to 10

(d) 12 to 9                     (e) 1 to 10                (f) 6 to 3

(a) Half. (b) One fourth. (c) One fourth. (d) Three fourth. (e) Three fourth. (f) Three fourth.
