Answer 1

4753 seems to me like the right one

Answer 2

Answer: $4753$

Step-by-step explanation:

Given: The mystery number is a four-digit number.

The digits used to make the number : 5, 4, 7, and 3.

Since , 5 and the 7 are the two middle digits.

Then , the number would look like $-57-\ or\ -75-$

The 5 comes after the 7.

Then , the number would look like $-75-$  [i.e.  $-57-$ is not representing  the mystery number]

The 3 is not the first digit, then 4 must be the first digit.

Hence, the mystery number should be : $4753$
