To solve this problem, we can start by considering the numbers that meet all three conditions: less than 30, with a digit sum of 10, and even.
We can begin by listing the possible numbers and checking which ones meet the given criteria:
- 12 (1 + 2 = 3, not 10)
- 14 (1 + 4 = 5, not 10)
- 16 (1 + 6 = 7, not 10)
- 18 (1 + 8 = 9, not 10)
- 20 (2 + 0 = 2, not 10)
- 22 (2 + 2 = 4, not 10)
- 24 (2 + 4 = 6, not 10)
- 26 (2 + 6 = 8, not 10)
- 28 (2 + 8 = 10)
From this list, we see that the only number that satisfies all the conditions is 28.
Therefore, the number you are thinking of is 28.
