652923

Sum should be 11 for any 3 pairs.
So possible combinations are (2,9),(3,8),(4,7),(5,6).
This shows 0 and 1 is not there.
Let we take no is "abcdef"
Given that,
d = b+4;
c = b-3;
hence,
d = c+7;
hence c must be 2.
hence d = 9;
hence b = 5;
also a = 3e is given
hence a = 6 & e=2.
And f = a-3
=6-3
=3
3 pairs sum of 11 are (6,5)(2,9)(9,2)
Hence number is 652923
