Six numbers 1, 2, 3, 4, 5 and 6 are written on different faces of a dice. Two positions of this dice are shown in the figure. Find the number on the face opposite to 3.

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 3 so we will take the dice in which 3 is included.

From both positons,

So, 6 is on opposite face of 3.

Thus, option B is correct.
