ita 86

To find the number that is greater than 30 and less than 40, and whose digit sum is 10, we can follow these steps:

1. Start by listing the possible numbers that meet the first condition: greater than 30 and less than 40. The numbers that fall into this range are 31, 32, 33, 34, 35, 36, 37, 38, and 39.

2. To determine which of these numbers has a digit sum of 10, we need to add the digits of each number individually and see if the sum equals 10.

- For 31: 3 + 1 = 4 (not equal to 10)
- For 32: 3 + 2 = 5 (not equal to 10)
- For 33: 3 + 3 = 6 (not equal to 10)
- For 34: 3 + 4 = 7 (not equal to 10)
- For 35: 3 + 5 = 8 (not equal to 10)
- For 36: 3 + 6 = 9 (not equal to 10)
- For 37: 3 + 7 = 10 (equal to 10)

3. From the numbers we listed, the only number that has a digit sum of 10 is 37.

Therefore, the number that is greater than 30 and less than 40, and whose digit sum is 10, is 37.
