Given Number: 4 2 1 5 7 9 3 6 8
Ascending order: 1 2 3 4 5 6 7 8 9
Hence the required pairs are 12, 49, 16
7 4 2
7 4 6
7 4 1
7 4 6
Only at these placees 4 is preceded by 7 but not followed by 3
Clearly, A?s new position is 15th from the left. But this is the same as B?s earlier position which is 9th from the right.
