Is it applicable for each case?
Or it can be Applied only when we have a divisor as 9?
Please explain.

In this problem we find the sum of the digits will be (29+x).
So,
Instead of x you put the values of options what ever they given and Add both then find which option is exactly divisible by 9 that is our required answer.

@ALL.
481 * 673=> 4+8+1+6+7+3=29.
=> 29 is add the two digit => 2+9=11.
=> 11-9=2.
Then 2 is the answer.

9=9.
18-----1+8=9.
27------2+7=9.
99------9+9=18.
The sum of digits is divisible by 9 then the digit is divisible by 9.
Here, the sum of digits is 29 if 7 is added then it becomes 36 which is divisible by 9.

Hi friends it is very very simple question why are all using different methods follow this method it is simple and superb.
Given that:
= 4+8+1+X+6+7+3 = X+29 (add all numerical).
In this he is given total value must be divided by 9.
Now 29/9 = 3.2222 (leave all numerical after point).
3*9 = 27.
Total 29.
Difference between them is 2. Now Subtract 9 from 2 we get the answer "7".

Correct if I'm wrong my solution is this.
4+8+1+x+6+7+3.
4+8+1 = 13.
6+7+3 = 16.
So therefore: 16+13 = 29.
2-9 = 7.
At the last part of my solution is it correct?
4+8+1+x+6+7+3.
4+8+1 = 13.
6+7+3 = 16.
So therefore: 16+13 = 29.
2-9 = 7.
At the last part of my solution is it correct?
