Solution
The correct option is A 6
No. of faces on the top faces of the dice (I), (II) and (III) are 5, 1 and 5 respectively.
Therefore, Total of these numbers = 5 + 1 + 5 = 11
No. of dots on the top faces of the dice (IV), (V) and (VI) are 1, 3 and 1 respectively.
Therefore, Total of these numbers = 1 + 3 + 1 = 5
Required difference = 11 - 5 = 6
