Accepted Answer

We have to make the greatest and the smallest $4$ -digit numbers using any four different digits with digit $9$ is always at tens place.

For the greatest four-digit number, we will put the largest digit at the largest place value and then the next largest digit at the next largest place value and so on. But $9$ will be at hundreds place.

The largest digit is $9$ , but, $9$ will be at hundreds place as given. So, the next largest digit is $8$ , so, $8$ will be at thousands place. The next largest digit is $7$ , so, $7$ will be at tens place and next is $6$ which will be at one's place.

Therefore, we get the largest four-digit number as $8976$ .

To write the smallest four-digit number, we will put the smallest digit at the largest place value and then the next smallest digit at the next largest place value and so on. But $9$ will be at hundreds place.

The smallest digit is $0$ , but we cannot start a number with zero. So, we take the next smallest digit which is $1$ so, $1$ will be at thousands place. Now, $0$ will be at tens place and the next smallest digit is $2$ which will be at one's place as hundreds place is fixed with $6$ .

Therefore, we get the smallest four-digit number as $1902$ .

Hence,

Greatest $8$ $9$ $7$ $6$

Smallest $1$ $9$ $0$ $2$

Make the greatest and the smallest $4$ -digit numbers using any four different digits with digit $9$ is always at hundreds place.
