The digit appears eleven time from 1 to 100.
Let's solve it a step at a time. For the first digit, how many choices do you have? 9 You can choose 1..9 but not 0, so that's nine choices for the most significant digit. For the second digit, how many choices do you have? 10 It can be 0..9. For the third digit, you also have 10 choices. Choosing one digit doesn't limit your choices for other digits and mirrored numbers (e.g. 123 and 321) are different, so all choices make a unique number. So the total is the product of our three choices: 9x10x10
This is not possible, since there are only five single digit odd numbers, which are 1, 3, 5, 7 and 9.
In such cases, you should compare one digit at a time, from left to right, until you find a digit that is different in the two numbers. That is, compare the first digit (after the decimal period) with the first digit, the second digit with the second digit, etc.

Definitely earlier than the year 2000. In April 2000, Portsmouth moved from six-digit local numbers to eight-digit numbers, as well as changing to the new, short area code of 023. (For example, Portsmouth City Council's number changed from 822251 to 92822251.) Instructions at the time referred only to how to convert six-digit local numbers to eight-digit numbers, so it is reasonable to assume that no five-digit numbers remained at that time.
Prior to the conversion to area code 029 with 8-digit local numbers in the Big Number Change in 2000, Cardiff was area code 01222 with 6-digit local numbers. If you go back in time, it is quite likely that Cardiff had 5-digit local numbers, and may also have had a mix of 5- and 6-digit numbers for some time.

Well, isn't that a happy little question! To arrange numbers by their terminal digit and middle digit, you simply look at the last and middle numbers of each set and organize them accordingly. It's like painting a beautiful landscape - just take your time, be gentle with yourself, and enjoy the process of creating something unique and special.
