      Solution

      3649285: Difference = (3 + 4 + 2 + 5) – (6 + 9 + 8) = 14 – 23 = 9
      2517846: Difference = (2 + 1 + 8 + 6) – (5 + 7 + 4) = 17 – 16 = 1
      1938427: Difference = (1 + 3 + 4 + 7) – (9 + 8 + 2) = 15 – 19 = 4
      7428516: Difference = (7 + 2 + 5 + 6) – (4 + 8 + 1) = 20 – 13 = 7
      None of them is divisible by 11.
