Answer 2

Answer:

9

Step-by-step explanation:

The difference between any number of four digits and the number formed by using the digits in the reversed order is exactly divisible by 9.

For example, 1234 is a 4-digit number if we reverse it then it would be4321.

Difference =4321−1234=3087

3087÷9=343

If we take another number 2345 and reverse it5432 and subtract it then,

5432−2345=3087

3087÷9=343

Hence, the difference between any number of four digits and the number formed by using the digits in the reversed order is always divisible by 9.
