Albert remarked that even when it is turned upside down, the number plate of his car still made sense.

He observed that this would however increase the registration number on it by 8505.

Given, all of the four digits in the number is different, find out what was his car license number?

I agree with cruncher. If you turn 1096 upside down, you have 9601, which is greater than 1096 by 8505. Are we missing something here?
