Solution

The correct option is C 3
On subtracting 3 from the middle digits, the numbers become : 559,332,524,341,412
Now, on reversing the positions of digits, we have : 955,233,425,143,214
Arranging these numbers in descending order, we have :955,425,233,214,143
The middle number is 233 and its last digit is 3.
