Explanation:
Let's consider a number with three digits i.e. abc.
The value of this number can be expressed as follows:
abc = 100a + 10b + c
When we subtract the sum of the digits from the number, we get:
(100a + 10b + c) - (a + b + c) = 99a + 9b
This can be simplified as:
99a + 9b = 9(11a + b)
Therefore, we can see that the resulting number is always divisible by 9.
Conclusion:
Hence, the correct answer is option 'A' which states that the resulting number is always divisible by 9.
