      6          4          5          3          1          4          6          5          2          6 8          6          7          5          2          6          8          7          4          8 The digits which are repeated are '8', '6', and '7', so sum = (8 + 6 + 7) = 21. The digits which are not repeated are '5', '2', and '4', so sum = (5 + 2 + 4) = 11. Difference = (21 - 11) = 10.
