There is a magic combination as 1 3 5 7 9
8 6 4 2
as it is not problem in dividing 1 and 3 by interchanging them but there is a problem in dividing 5 as it is either divisible by 5 or 0 , since 0 is not allowed so 5 should be there .after placing another numbers we can get lot of combinations except 5 as it has to be at 5th position.
