Six numbers 1, 2, 3, 4, 5 and 7 are written on different faces of a dice. Two positions of this dice are shown in the figure. If both the even numbers are written on opposite faces of the dice, find the number on the face opposite to '1'.

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

3 is common in both the positions.

From both the positions,

So, 3 is on opposite face of 1.

Thus, correct option is (d).
