Form the smallest 4-digit number with 4 in the tens place by using different digits.
Answer:
1042
- 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. - Now, we will place 4 in the tens place.
- 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.
- Hence, 1042 is the smallest 4-digit number with 4 in the tens place.
