These are the types of puzzles that most lawyers should be good at. I remember these types of questions on the Law School Admissions Test.

It appears these two conditions make these puzzles much easier to solve.
That gives us Casper's 6 and 9 right there.

But I made a huge mistake that allowed the 7 to get between the 6 and the 9. I will do better next time

413 Nothing is correct
Not possible to eliminate anything based on the first clue. The second clue eliminates 4 and 1 from the first clue, so we know one of the digits in the code is 2 and that it is also the first digit of the code.
532 Two numbers are correct but wrong places
We already know from the first two clues that 2 is the first digit. We also know from the second clue that 3 is not one of the digits. So based on the third clue we know that 5 will be one of the digits and we know from the first clue that the 5 will have to be the second or third digit.
347 One number is correct but wrong place
We know from the second clue that 3 and 4 are not part of the code. So 7 is part of the code and it must be the second digit because 2 is the first digit (clue #1) and 7 is not the third digit (clue #4). The only place in the code left for 5 is the third. Code is 275
751 Two numbers are correct but wrong places
This clue is not necessary, but confirms that 7 and 5 are in the code but 7 is not the first digit and 5 is not the second digit. Recall that 1 is not in the code (clue #2)
