That is a trick question. 10 is the same number as 10.000, it is merely expressed with fewer significant digits. There are no numbers between one number and itself.
100. Palindromic numbers for the range 10000 to 20000 are 5 digits numbers of the form abcba. The first digit ('a') must be '1'. There are 10 possible digits for 'b' (0-9) and for each of these 10 possible digits for 'c' Thus there are 1 x 10 x 10 = 100 palindromic numbers between 10000 and 20000.
