Let’s solve the riddle step by step.
We are looking for a 3-digit number from this list:
```
327 185 492 602
256 42 813 523
```
But note: one of them is
not a 3-digit number — that’s
42. So we can eliminate it right away, because the riddle says “I am a 3-digit number.”
Remaining candidates:
→ 327, 185, 492, 602, 256, 813, 523
Now let’s go clue by clue.

Clue 1: *My hundreds digit is not 5.*
So we eliminate any number where the first digit (hundreds place) is 5.
Look at the list:
- 327 → hundreds = 3 → OK
- 185 → hundreds = 1 → OK
- 492 → hundreds = 4 → OK
- 602 → hundreds = 6 → OK
- 256 → hundreds = 2 → OK
- 813 → hundreds = 8 → OK
- 523 → hundreds = 5 →
✘ Eliminate!
Now left with:
→ 327, 185, 492, 602, 256, 813

Clue 2: *My tens digit is even.*
Tens digit is the middle digit.
Check each:
- 327 → tens = 2 → even →
✔
- 185 → tens = 8 → even →
✔
- 492 → tens = 9 → odd →
✘ Eliminate
- 602 → tens = 0 → even →
✔
- 256 → tens = 5 → odd →
✘ Eliminate
- 813 → tens = 1 → odd →
✘ Eliminate
Left with:
→ 327, 185, 602

Clue 3: *My ones digit is less than 4.*
Ones digit is the last digit.
Check:
- 327 → ones = 7 → 7 < 4? No →
✘ Eliminate
- 185 → ones = 5 → 5 < 4? No →
✘ Eliminate
- 602 → ones = 2 → 2 < 4? Yes →
