Answer is 2..

Average is 7 x 3 = 21

Median is 9, so the sum of the other two box = 12! (21-9)

Now, the heavier box shud be more than 9 (as 9 is the median)

Assuming all weights are INTEGERs!

The min weight of the hevier box wud be 9+1 = 10!

Hence the max weight of the lightest box = 12-10 =2!

Why can't it be equal to 9?
