Everyone, guess what the password is?

Let me analyze the method that cruelfox mentioned in the first three points. First, eliminate the number 2 according to points 1 and 2. Then, according to point 3, determine that there are 69 in the number. According to point 1, determine that the position of 6 is in the ones place. According to point 3, determine that the position of 9 is in the hundreds place. According to point 2, determine that the number in the tens place is 8. So the final answer is 986

1 first knows that 9 is the correct number and is ranked first. 2 From the first clue, one of 2 and 6 is correct, and combined with 1, it is 6 and is ranked third. 3 is eliminated by the third clue and the first two, and the middle one is 8.

The correct value is 986

Could it be 211/985?

986, the first three items are sufficient. The last two items are redundant.

When the first person announced the answer, I realized that my IQ was so low.

The first three cannot be confirmed, right? ? ?

I pushed it carefully and it turns out that the first three are enough. Master!

You are such an expert! I am doubting my IQ. I feel like all the math I learned before is no longer good enough.

From the first and second items, we know that 2 is not a number in the password.

Combining the above conclusion with item 3, we can know that: the password contains 9 and 6. Combining item 2, we can know that the other number in the password is 8.

Combined with the first item, we know that 6 is the correct number and in the correct position. 9 is not in the correct position in the third item, so it should be in the first position, so the number is 986.
