There are 90 palindromic numbers between 100 and 1000
The sum of all palindromic numbers from 1001 to 9999 is 495000.
As 20569.8 is not palindromic, any number that is like it must contain that property and similarly be non-palindromic, so no.

Oh, what a happy little question! There are 90 three-digit palindromic numbers in total. You see, they start at 101 and end at 999, with each one bringing its own unique charm and symmetry to the canvas of mathematics. Just imagine the joy of exploring all these lovely palindromic numbers!
No.
No. For instance, 101 is not divisible by 11.
Nobody went out to create them: some numbers simply happen to be palindromic and others don't.
