Let's try to solve this 3-digit crack-the-code puzzle. Firstly assign the alphabets A, B, and C to the 3 digits in the question.

Study the 1st hint: One Number out of 1 4 2 is correct and well-placed. This means that only one digit is true among the digits 1, 4, and 2.

Building upon this, the second clue: "Two Numbers out of 3 0 9 are correct and well-placed". Combining insights from the first and second clues, we narrow the pool of potential 3-digit combinations to 1, 4, 2, 3, 0, and 9.

The third clue "Nothing is Correct" comes into play, eliminating 4 from contention and refining our set to 1, 2, 3, 0, and 9. The fourth clue states "One Number out of 1, 3, and 9 is correct but wrongly placed". This leaves us with 2 and 0 as the remaining candidates for the final 3-digit code.

Combining information from the second and fourth clues, it becomes clear that the third digit is either 3 or 9. Applying the first clue "One Number is correct and well placed" to our extended set, we ascertain that C equals 2. So our 3-digit number looks like A B 2.
