Can you arrange the following figures in two groups of four figures each so
that each group shall add to the same sum?
1 2 3 4 5 7 8 9
If you were allowed to reverse the 9 so as to change it into the missing 6 it
would be very easy. For example, 1,2,7,8 and 3, 4,5,6 add up to 18 in both
cases. But you are not allowed to make any such reversal.
