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 6 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.
