There are multiple answers. The only criteria is that the last digit be one third of the second to last ( the tens digit ). So, 731 works as does 362 and 1,631, 2,162 and 11,162. You can also do 111,111,131.
That means multiply it by 2. If your tens digit is 3, your ones digit is 6.
Let the ones digit be represented as ( x ). Since the ten digit is 9 more than the ones digit, it can be expressed as ( x + 9 ). However, since digits can only range from 0 to 9, the only solution is when the ones digit ( x ) is 0, making the ten digit 9. Therefore, the two-digit number is 90.

The population total must be in the range of 800 to 1000, with a digit sum of 21 and the same digit in the ones and hundreds places. The only number that fits these criteria is 993, as it has the same digit (9) in the hundreds and ones places, and the sum of the digits (9 + 9 + 3) equals 21. Therefore, the village's population is 993.

The number is 84.
The ones column are in single digits and if there are none then the 0 digit is used.
That means multiply it by 2. If your tens digit is 3, your ones digit is 6.
Let the ones digit be represented as ( x ). Since the ten digit is 9 more than the ones digit, it can be expressed as ( x + 9 ). However, since digits can only range from 0 to 9, the only solution is when the ones digit ( x ) is 0, making the ten digit 9. Therefore, the two-digit number is 90.

Three-digit ones refer to the individual digits in the ones place of a three-digit number, while two-digit tens refer to the digits in the tens place of a two-digit number. In general, a three-digit number (ranging from 100 to 999) will have a greater value than any two-digit number (ranging from 10 to 99). Therefore, three-digit ones are greater than two-digit tens.
Since the first digit cannot be zero, the possibilities are 1054, 1216, or 3034.
