The puzzle contains a trick.
If the available numbers are all odd (for example: 1, 3, 5, 7, 9, 11, 13, 15), then three odd numbers can never add up to 30, because:
- Odd + Odd = Even
- Even + Odd = Odd
Since 30 is even, it’s impossible using three odd numbers as they are.
The intended solution is to turn the 9 upside down to make a 6. Then you can choose:
- 11 + 13 + 6 = 30
So the answer is:
✅ 11 + 13 + 6 = 30 (by flipping the 9 to become a 6).
