Which direction will you face if you start facing
(a) east and make
of a revolution clockwise?
(b) east and make 
of a revolution clockwise?
(c) west and make 
of a revolution clockwise?
(d) south and make one full revolution?
(Should we specify clockwise or anti-clockwise for this question? Why not?)
When we revolve one complete round in either clockwise or anti-clockwise direction we complete an angle of 360° and the two adjacent directions will be at 90°.
(a) If we start from East and make half of the complete revolution clockwise, we will be facing the west direction.
(b) If we start from East and make one and half of the complete revolution clockwise, we will be facing the west direction.
(c) If we start from West and make three fourth of the complete revolution anti-clockwise, we will be facing the north direction.
(d) If we start from South and make a complete revolution clockwise or anti-clockwise, we will be facing the South direction again.
