Gaurav Agrawal (IAS) answered very intelligently in 2014 using his imagination as 3! + 3! + 3! + 3! + 3! = 30  This question is asked so many times.. all credit goes to him.  The following ways are my suggestions.
I can answer this question in many ways using the factorial function.

3! + 1 + 3 + 9 + 11          = 30
1 + 5 + 7 + 3! + 11               = 30
3! + 3! + 3! + 11 + 1             = 30
3! + 3! + 11 + 5 + 1               = 30
11+ 1 + 1 + 3! + 11              = 30
15 + 3 + 3 + 3 + 3!              = 30
13 + 1 + 1 + 9 + 3!            = 30
13 + 1 + 3 + 7 + 3!            = 30
13 + 5 + 3 + 3 + 3!            = 30

======================================================
You need one operator for which the result is an even number with an input being an odd number.  Factorial is one.  Probably there are other operators too.

what are the 3 types
3 ! => 3 factorial. it is a mathematics operator like + or /.. 3 ! = 3 * 2 * 1 = 6.
no
what do you want ?
please clearly mention.. what do you mean by " 3 types "
