You read some of the questions wrong. For 8, it’s asking you what percent of the questions whose answers are A appear between 1-10. For instance, if there are 3 questions that are A from 1-10, and 0 questions from 11-15 whose answers are A, then the answer would be 0%.
Oh, yeah. The first four were extremely easy. I actually messed up a couple times after that and had to retrace my steps because there are so many moving pieces! Great job. :)
Just one thing, it didn't matter because I worked around it a different way, but I found the wording of question 6 to be ambiguous: "How many unique answers are there in the first 3 questions?"
I couldn't tell if it meant total number of unique letters used (e.g. if D, C, D, then 2, because D & C are different letters), or total number of answers that weren't repeated (e.g. if D, C, D, then 1, because D as an answer is in the set twice, and therefore only C is unique).
Question 9: Answer"A" is impossible (3.75 "A"s?)
Therefore the answer to question 10 must be "A".
Therefore the answer to question 11 must be "A", too.
Therefore the answer to question 8 must be "B".
And the ring of illogic is closed.
Where am I wrong?
