A certain number of distinct digits are written on a piece of paper. Using all those digits, how many different numbers can be formed?
1. If we omit the first and the last digit that was written on the paper, then the total numbers that can be formed using the remaining digits is \(120\)
2. If we omit the last three digits that were written on the paper, then the total numbers that can be formed using the remaining digits is \(24\)
The OA is E
