THE LOGIC;

Assuming the dice in figure ii, to be rotated so that the 5 dots appear at the same position as in figure i and 01 dot appears at the same position as in figure i

Then, from the 2 figures, 2 dots appear on the top face and 4 dots appear on the bottom face.

Since, these 2 faces are opposite to each other,

Thus, 2 dots are contained on the face opposite to that containing 4 dots.
