The answer is 65! Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let the number be written as xy
x-ten's place
y units place
x+y=11.....................1
(10x+y)-(10y+x)=9
10x+y-10y-x=9
9x-9y=9
/9
x-y=1......................2
Add (1) & (2)
2x=12
x=6
y=5
the number is 65
