Answer:

1042

Step by Step Explanation:
  1. We know that there are ten different digits, i.e., 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, where 0 is the smallest of all.
    But we cannot write 0 in the thousands place as the number, thus formed, will actually become a 3-digit number.
    Therefore, we must place it in the hundreds place.
  2. Now, we will place 4 in the tens place.
  3. Since, we have to form the smallest 4-digit number, we need to choose the smallest remaining digit, i.e., 1 and place it in the thousands place while placing 2 in the ones place.
  4. Hence, 1042 is the smallest 4-digit number with 4 in the tens place.
