Answer 1

@Krishna Teja Yeluripati
5! = 120 numbers possible, if we'll sum numbers with mirrored digits (12345 and 54321, 51324 and 15342...) we get 66666 for each pair of numbers; 66666 * 60 = 3999960

Answer 2

3999960

Answer 3

5!=120

12345
+54321 120/2=60
------------
66666

66666
x60
-------------
3,999,960

Answer 4

120/5=24
24*120=2880?
Just a guess that's wrong.
