Question

Sample Table structure

I will ignore the repeated rows.

6+9
6+10
6+7+8
6+7+9
6+7+10
6+8+9
6+8+10
6+9+10 
6+7+8+9
6+7+8+9+10

Answer 1

This makes no sense. What about NULLs? What about duplicate values? You have rows, so you have many combinations. We know that this set totals to 39, so there is no subset totals to half of any odd number.  19.5
in this case. 
None of your examples are
even close! 
 6+7 = 13
the remaining rows 8+9+10 = 27, so you failed!
