CLUES TO THE ANSWER

Of the numbers 7,6,8,5, only one number is correct but incorrectly placed.

Of the numbers 1,9,3,7, only two numbers are correct but also incorrectly placed.

Of the numbers 5,2,0,1, only one number is correct but is correctly placed.

Of the numbers 6,5,2,7, NONE of the numbers are correct.

Of the numbers 8,5,2,4, Two numbers are correct but wrongly placed.

ANSWER

6,5,2,7 are incorrect, so of the numbers 7,6,8,5, only 8 is correct.

Of the numbers 1,9,3,7, we have already disqualified 7, so 1,9,3 are still possibilities.

For the numbers 5,2,0,1, 5 and 2 are incorrect, so one of 0 and 1, are still possibly correct and is in the correct position.

For the numbers 8,5,2,4, 5 and 2 are incorrect, so we can deduce that 8 and 4 are correct. However they are wrongly placed so the real number is 4,x,x,8. Still with us?

Let’s go back to numbers 5,2,0,1. We can choose between 0,1 and we now know that 1 is impossible because 8 is already occupying that spot. We now have 4,x,0,8.
