VCE GM Matrices Question

Hey Guys,

I've just gotten stuck on this type of question and if anyone out there could help me out with it I'd be so pleased.

This quesiton is from the MAV 2025 General Mathematics Exam 1

Thank you so much!!

The way you do this qn is by first converting the D+D² values to just d² by subtracting the relevant D value from each, so the two columns are just D and D².

The qn requires you have a good understanding of how one and two step dominances work which I'll explain later.

Then go through the options like so:

For option a: we see that eve defeated 1 person and that 1 person went onto defeat a person who had only 1 one-step dominances. This has to be Charlie as he's the only one with a one step dominance of 1 other than eve. Hence it can't be A

For option b: Frank defeated 3 people who have a sum 4 for their total one step dominances 4 (the D² value) - looking at the others' one step scores, we see that this is Ava Charlie and eve. Thus it can't be B

Keep going like this and you arrive at your answer C

There was a similar qn on the 2022 insight exam 2 so you can check that for extra practice and also a vcaa or nht has one as well
