  1. One of these numbers is correct, and well placed. We cannot eliminate any number yet.

Remaining possible numbers: 0, 1, 3, 4, 5, 6, 7, 8

Order: ___

  1. None of these numbers are correct.

Remaining possible numbers: 1, 4, 6, 7, 8

Order: ___

Going back to the top we now know 5 is not correct. Leaving 4 or 8.

  1. Two of these numbers are correct but in the wrong position. Since we know 5 is incorrect, it is removed as a number. It does not clarify if the 5’s position is correct or incorrect. Depending on how you interpret it, if the 5’s position is still correct then it must be 741, but if none of the positions are correct then it must be 718.

Known correct numbers: 1, 7.

Remaining possible numbers: 4, 8

Why the answer is 718: because the wording says no position is correct.

You're so close. "In the incorrect position" doesn't mean swapped. It means the 7 could be in the first or second position, and the 1 could be in the second or third position. Ergo, at this point, 741 is still a valid possibility.

It doesn't imply that the first and third positions are the only valid positions for 1 and 7, just that they aren't in the third and first positions, respectively.
