-- Since she answered 86 percent of the questions correctly, she answered the remaining 14 percent of them incorrectly. -- 14% of 100 questions is 14 questions.

To get at least 64% you can miss at most 100 - 64 % = 36 % Percent means "out of 100" 36 % of 56 = 36/100 x 56 = 20.16 → Can miss 20 questions.

You got 89 percent. Hence, you answered 89/100*150 = 133.5 questions. hence you missed 150 - 133.5 = 16.5 questions.

At most 16 questions. Percent means "out of 100" → 85% of 108 = 85/100 × 108 = 91 4/5 Which means unless you get 92 you will not get at least 85 % Therefore you can miss out on 108 - 92 = 16 questions at most and still get at least 85 %

You can lose 44% which is 150*44/100 = 66. But then you must get every one correct!

70 PER CENT means 70 out of a hundred... so you missed 30

I think it depends on the grading scale. However, if each was worth a point then maybe you could only miss 15 questions to get an 85%.
