>>16874123>A) 682: 1 fully correct>B) 614: 1 correct number but wrong position>C) 206: 2 correct numbers but wrong positions>D) 738: none correct>E) 780: 1 correct number but wrong position(D) and (E) lets us know 0 is present, but not in the last position, thus 0 must be first or second position.
>0xx; x0xWe know 0 is present, and (B) says 2 correct numbers are in the wrong position, and from (D) and (E) we know 0 is not in the last position, therefore 0 must be in the first position.
>0xxFrom (A) (B) and (C) we know 2 must be in the final position. We already know 0 occupies the first position. We know from (D) that 8 is not present, so the one fully correct number in (A) cannot be 8. We also know it cannot be 6 because 0 already occupies the first position.
>0x2Now, we can conclude from (B) that the number in the second position is 4. 1 is already in the second position, and the clue says the correct number is in the wrong position. We have already deduced the numbers occupying the first and last positions, so it cannot be 1. It ca
Therefore, the answer must be
>042
