2. For a two-digit number, the number of the tenth digit is 3 less than the number of the second digit. If the sum of the number of the tenth digit and the number of the second digit is equal to this two-digit number, find this two-digit number.
For two-digit numbers, the tenth digit is twice as large as the first digit. If the number on the tenth digit is reversed from the number on the single digit, the two digits are 36 less than the original two digits, so find the original two digits.
4. Two-digit numbers. One digit is ten digits. If the number of ten digits is reversed with the number of one digit, the two digits obtained are 54 less than the original two digits, so find the original two digits.
5. A two-digit number, the number of one digit is twice that of ten digits. If the tenth digit is swapped with the second digit to get the second digit, then add 1 to the second digit and subtract 1 from the first digit to get the third digit. If the third digit is exactly 2 of the original digit,
6. A three-digit number is an integer multiple of 15, the sum of the three digits is 18, and the difference between the hundred digits and the ten digits is 1. Find this three-digit number
7. The difference between three digits and two digits is 500, and the sum of these three digits is 22. Find these two numbers.
8. There are six figures (1abcde). Multiplied by 3, it becomes abcde 1. Find these six figures.
9. Three digits of three digits are three consecutive natural numbers from left to right. Add 1 before it and 5 after it to get a five-digit number, which is 645 times more than three digits. Find these three numbers.
