The positive five-digit integers that use each of the digits 1, 2, 3, 4 and 5 exactly once are ordered from least to greatest. What is the 60th integer in the list?

#1**+1 **

5!=120

so it looks like you want the middle one.

so it will start with a 3

How many are less than 30000? That would be 2*4!=48

how many start with 31? That would be 3! = 6

So another 6 will start with 32

So that means there are 60 that are less than 34000

**So the 60th one must be 32541**
