For a seven digit number, the number on each digit is different, and the sum is 36. What is the maximum number of the seven digit number?

For a seven digit number, the number on each digit is different, and the sum is 36. What is the maximum number of the seven digit number?

For a seven digit number, the number on each digit is different, and the sum is 36. The maximum value of the seven digit number is (9876510)

There is a seven digit number. The sum of the numbers on each digit is 55. If you add 2 to this number, you will get a new seven digit number. At this time, the sum of the numbers on each digit of the new number is 3, and the original number is 3______ ．

According to the meaning of the title, the sum of the new seven digit numbers is 3. It can be concluded that each digit in the new seven digit number only contains 3, 6 zeros, or 1, 2, 5 zeros, or 1, 1, 1, 4 zeros. Because the sum of each digit in the new seven digit number is 3, which is much smaller than the original 55, it shows that there is a continuous carry when adding 2

According to the meaning of the title, the sum of the new seven digit numbers is 3, which means that each digit in the new seven digit number only contains 3, 6 zeros, or 1, 2, 5 zeros, or 1, 1, 1, 4 zeros. Because the sum of each digit in the new seven digit number is 3, which is much smaller than the original 55, it means that there is a continuous carry when adding 2, and every carry, the sum of each digit is less Therefore, carry (55 + 2-3) / (10-1) = 6 The results show that: (1) when there are only 3 and 6 zeros, there is only 3000000, then 3000000-2 = 2999998, 2 + 5 × 9 + 8 = 55, which is consistent; (2) when there are only 1, 2 and 5 zeros, there is only 2000001, 2000001-2 = 1999999, 1 + 9 × 6 × 9 = 55, which is consistent; (3) when there are only 1, 1, 1 and 4 zeros, there is no consistent bar So the original number is 2999998, 1999999. So the answer is: 2999998 or 1999999
