Two different positions of the same dice are shown below, the six faces of which are numbered 1 to 6. Which number is on the face opposite the face showing 1?

2

Step 1) In figure 1 and 2, (1) is common

Step 2) The number ‘1’ is common in both the dice. In order to find out, the number appearing on the opposite face, rotate the dice in a clockwise direction with the common number as the reference.

Step 3)   1       3       6

               1       5       4

Step 4)  

3  is opposite  to 5

6  is opposite  to 4

Therefore

1  will be opposite  to 2
