Six numbers, 7, 8, 9, 10, 11 and 12 are written on different faces of a dice. Three positions of this dice are shown here. Find the number on the face opposite 12.

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

we need opposite of 12 so we will take the dice in which 12 is included.

From second and third positons,

So, 11 is on opposite face of 12.

Thus, option C is correct.
