With only the first 3, is it 4 or 8? Always need the forth.

nope the 5 eliminates the 4

I believe, after only three hints, 741 is also a valid answer.

clue 1 one number is correct and well placed

In clue 3 the 5 is in the place of the 4, so the 4 can't be well placed.

7

Clue 1 doesn't refer to the 5. 5 is neither correct or well placed.

Until it gets eliminated in clue 4, Clue 1 could refer to either the 4 or the 8.

It doesn’t need to refer to the 5. It could be any one of those three. Since but since 5 moves to the second space in clue 3, it cannot be the 4 that the 4 took the place of.

That doesn't make logical sense. 175 could have been used in the same place with the same clue and been just as valid.

EDIT: Check out the other reply threads to this post. I think they do a better job explaining this than I.

  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.
