Three numbers, 1, 2 and 3, and three letters, X, Y and Z, are written on the different faces of a dice. Two positions of this dice are shown in the given figure. Find the letter/number on the face opposite to Y.

​

Logic: In these types of dice problems, we should write all three numbers in clockwise or anticlockwise from a fix common number.

1 is common in both positions

From both positions,

So, 1 is on opposite face of Y.

Thus, option D is correct.
