(6+5+6+8+x) / 5 = 6
(25+x) / 5 = 6
5 + x/5 =6
X/5 = 1
X = 5
The answer is x=70 degrees

Not completely sure how to answer your question but all 20 questions where worth 5 points each which she would have gotten a 100 if she got all right but she got 15 which her score would be 75. I think in a ratio of correct to incorrect would be 75:100 , I'm not sure completely.
