Answer by ankor@dixie-net.com(22740)   (Show Source):
You can put this solution on YOUR website! let t = tens digit
let u = unit
:
an odd number between 48 and 64.
t = 4, 5 or 6
the tens digit is greater than the ones digit
t > u; 49 is excluded
t = 5 or 6
and the difference between the two digits is 4.
t - u = 4
t = 6
6 - u = 4
u = 2, then 62, but that is an even number
t = 5
5 - u = 4
u = 1, then 51 has to be the number
