Six dice with upper faces erased are as shows. The sum of the numbers of dots on the opposite face is 7. If the dice (I), (II) and (III) have even number of dots on their bottom faces, then what would be the total number of dots on their top faces?

7 11 12 14

11

No. of dots on the top faces of dice (I), (II) and (III) are 5, 1 and 5 respectively. Required total = 5 + 1 + 5 = 11
