��
12 �> 21 ==> 9/12 = 0.75 or 75% increase from 12 to get to 21
45 �> 54 ==> 9/45 = 0.20 or 20% increase from 45 to get to 54
Since the percentage is a function of what the original two digit number is, the best we can do is find a formula for the percentage increase.
Let n be the initial (ten's) digit in the unswapped number (e.g. n=1 in 12):
Then our two digit number is 10n + (n+1) = 11n + 1
Swapping digits will always increase the number by 9 so the percentage increase is:
%
