Which numbers are possibly in there:

We know that either two of these are the correct numbers: 123/456

We know that 0 isn't the number and proved 2 is included as you couldn't put "0" in the first digit. This means only either 1/3 is correct.

That's even more confusing for the fourth answer. 7, 0 and 8 are not the numbers since either two from 4, 5 or 6 are the answers.

Narrowing it down to the possible numbers we have: 1, 2 (MUST), 3, 4, 5, 6, 9.

We know that "1" is the number in front from answer 5. This also disqualifies "3" as a possible number. Unless "1" IS DUPLICATED, we know the place value of "2".

Answer 7 still could not prove which either two from 4, 5 or 6 are included.

948280 is the key, proving 9, 4 and 2 are the numbers.

Now, the only numbers left is 1, 2, 4, 5/6, 9

Interestingly in answer 9, 5 is disqualified. Now the numbers must be 1, 2, 4, 6, 9.

Proved again in answer 10, 11 and 12.

Now moving to the green ticks:

The analysis above shows that 1 is the first digit.

1XXXXX

Possible locations:


 * XXX64X (Proved the place for 4 and 6)
 * 11211X
 * XXXXX6 (Now we know 6 is duplicated, so the second point shows that the place position of "2".)

Answer:
