Question

From the original position given in the diagram, D and B move one and a half length of sides in the clockwise and anticlockwise directions, respectively. Which one of the following statements is correct?

• A. Both B and D are at the mid-point between A and C.
• B. D is at mid-point between A and C; and B at the corner originally occupied by C.
• C. B is at mid-point between A and C; and D at the corner originally occupied by A.
• D. Both B and D are at the mid point between A and the original position of D.
• E. B is at the mid-point between A and the original position of D; and D is at the mid-point between the original position of B and C.

Answer 1

The correct option is E B is at the mid-point between A and the original position of D; and D is at the mid-point between the original position of B and C.

After the movements, the final positions of A, B, C and D are as shown in diagram (ii), We observe that B is at the mid-point between A and the original position of D and D is at the midpoint between the original position of B and C.
