6 piano classes for 9 people (4 female and 5 male). You are told that two classes will have more than two people, and the other four classes will have exactly one.

One class is already given to you (I+L), and you know P's class will have two other people (P_ _). So you know these are the two classes that will have more than one person. So the game will be distributed something like 3-2-1-1-1-1. The 3 person class being the one with P and two others, and the 2 person class which is already given to be IL.

3rd rule: K is the first female, but not first student. So the earliest she can be is in the second class. This means the the earliest that any other female can be is the 3rd class.
4th rule: IL > G > P
5th rule: G > O

Question 20: Only N and S can attend the first class. N is not one of the choices, so S (answer e) is the answer. You know this because none of GHIL can be first since they are female and must come after K which can't be first either (this eliminates all the females, as well as L since he is in a class with I). O can't be first because it has to come after G, and P can't be first because it comes after IL and G.

Knowing that only N or S can be first will probably help with the other questions. Try them out
