Step 1:- Think of any number consisting of 5 consecutive digits in ascending order.
Step 2:- Reverse the digits to obtain another number.
Step 3:- Find the difference of both the numbers. It always remains same, i.e. 41976.
Example 1:- Let’s take the number 34567.
After reversing the digits we get 76543.
Difference of both the numbers is, 76543 – 34567 = 41976.
Example 2:- Take the number 56789.
Reverse the digits – 98765
Difference of both the numbers is, 98765 – 56789 = 41976
Note:- For any number, consisting of 5 consecutive digits in ascending order, when subtracted from the number obtained by reversing the digits, leaves always a unique number, i.e. 41976. Thus, 41976 is a UNIQUE NUMBER. Its a five digit Unique number.
