I am an odd number

I am less than 100
The sum of my digits is 12
What am I

75, 93, 57, 39

Which one?

57

To find the answer, we need to think about the given criteria.

First, you are an odd number, which means the last digit must be 1, 3, 5, 7, or 9.

Next, the number must be less than 100, which means the two digits cannot be greater than 99. Since the sum of the digits is 12, the possible combinations are limited. We can start by examining all the possibilities:

- When the last digit is 1, the remaining digit must be 11. However, the sum of the digits, 1 + 11 = 12, does not match the given criteria.

- When the last digit is 3, the remaining digit must be 9. However, the sum of the digits, 3 + 9 = 12, does not match the given criteria.

- When the last digit is 5, the remaining digit must be 7. The sum of the digits, 5 + 7 = 12, matches the given criteria. So, the number is 57.

Therefore, if you are an odd number, less than 100, and the sum of your digits is 12, then you are the number 57.
