From the position given above, all move in the clockwise direction along 3/8 of a circle. From this position all are asked to move in the anticlockwise direction at an angle of π radians.
Now from this position in the previous question A and C move clockwise and B and D move anticlockwise at an angle of 135∘.
From this question A and C interchange their positions and B and D move anticlockwise along one-fourth of the circle. In this new position, which of the following is correct?
