If you know how permutations. This will be a lot easier for you. I'll attempt to explain so you dont keep asking the same type of questions. 

There are 30 teachers for 6 posts. For the first position, there are 30 possible choices. For the second position, there are 29 possible choices, and so on.

30 Permutation 6, or 30*29*28*27*26*25
