Crack the code

2 4 5 - One number is correct but wrong place.
4 6 3 - Two numbers are correct but wrong places.
5 7 8 - Nothing is correct.
5 6 9 - One number is correct but wrong place.

ANSWER


394 is the answer.

Explanation
If you take the second statement, 2 is incorrect from the first statement and 5 is incorrect from the fourth statement. Hence 4 is correct, but not on the second place. From the third statement, 4 is not on the first place. Hence 4 is on the third place.

From the fifth statement either 6 or 9 is correct. But combining it with the third statement, 6 is incorrect. Hence along with the first statement, 9 is correct and on the second place.

From the third statement, 3 is correct and on the remaining first place.

    1. Explanation:

      Step 1: Assume 9 is correct number


      Step 2: Assume 4 is correct number but wrong placed.

      (why not 2? If 2 was correct and well placed then they would have mentioned 2 numbers correct. Moreover in Step1, 2 is not well placed.
      Why not 5? Step 4 says nothing is correct. So 5 is incorrect number)


      Step3: we assumed 9 is correct number and well placed in Step1, so swap 3 and 4.
      Result :3 9 4


      Step4: nothg is correct

      Step5: As we assumed 9 is the correct number but wrong placed.



      So

      Answer is 394

  11. 9 is the correct number In row 1 that is well placed

    4 is the correct number in row 2 but wrongly placed

    4 is also the correct number in row 3 but wrongly placed
    (Automatically 4 must move to last position)

    3 is the 2nd number correct in row 3 but also wrongly placed so we move to 1st row

    Nothing is correct in row 4

    9 is correct in row 5 but wrongly placed
    And since they already told us in row one that 9 is correct and well placed so 9 for middle
