Answer: (i) Smallest 9-digit number:
To form the smallest 9-digit number, we need to arrange the given digits in ascending order. The smallest digit is 0, but we can't use it as the first digit (since it would make the number 8 digits long). So, we'll start with the next smallest digit, which is 1.
The smallest 9-digit number is: 1,023,456,789
(ii) Greatest 8-digit number:
To form the greatest 8-digit number, we need to arrange the given digits in descending order. The largest digit is 9, so we'll start with that.
The greatest 8-digit number is: 9,876,543,210
(iii) Difference of the numbers:
To find the difference, we'll subtract the smallest 9-digit number from the greatest 8-digit number:
9,876,543,210 - 1,023,456,789 = 8,853,086,421
(iv) X is at tons place:
Since X is at the tons place, we need to find the digit at the tons place (which is the third place from the right) in the number formed.
Let's take the smallest 9-digit number: 1,023,456,789
The digit at the tons place is: 3
