The number is a two-digit number. It is odd. The sum of the digits is 10. It is greater than 30 but less than 50. What is the number?

37

31, 33, 35, 37, 39, 41, 43, 45, 47, 49

To find the number, we need to follow the given clues step by step.

First, the number is a two-digit odd number. This means the number must be between 10 and 99 and cannot be even.

Next, we know that the sum of the digits is 10. So, we need to find two digits that add up to 10. The possible pairs of digits are (1, 9), (2, 8), (3, 7), (4, 6), and (5, 5).

Now, we are given that the number is greater than 30 but less than 50. Out of the possible pairs of digits, only (3, 7) satisfies this condition since the first digit must be 3 and the second digit must be 7 for the number to be within the given range.

Therefore, the number is 37.
