You can miss out 30% 30% of 150 = 150*30/100 = 45
You can only miss 16 points on a 100 point test in order to get an 84%. If the questions are worth 2 points EACH, you can miss 8. If the questions are worth 4 points each, you can only miss 4 questions.
100%-80%=20%10*.2=2Therefore you missed 2 questions.
You can lose 44% which is 150*44/100 = 66. But then you must get every one correct!
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%.
You answered 23 questions incorrectly.

-- 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 can only miss 16 points on a 100 point test in order to get an 84%. If the questions are worth 2 points EACH, you can miss 8. If the questions are worth 4 points each, you can only miss 4 questions.
You got 89 percent. Hence, you answered 89/100*150 = 133.5 questions. hence you missed 150 - 133.5 = 16.5 questions.
100%-80%=20%10*.2=2Therefore you missed 2 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 %

The answer to how many questions you can miss (assuming each question is worth 1 mark) is given below: ((100-90)/100) * 125 = 12.5 questions. You must round this down unless you can be awarded half marks. Assuming no half marks are awarded you can miss up to 12 questions on a 125 question test and score 90% or more.
90% of 27 = 27*90/100 = 24.3 So you MUST answer 25 questions - ie all but 2 - AND get them all correct!
