To achieve an 80 percent score on a 27-question test, you would need to answer 80% of the questions correctly. This means you can get 20% of the questions wrong. To calculate the number of questions you can miss, multiply 27 by 0.20 (20%) to get 5.4. Since you can't have a fraction of a question, you would need to round down to 5 questions. Therefore, you can miss 5 questions out of 27 to achieve an 80 percent score.
90% of 27 = 27*90/100 = 24.3 So you MUST answer 25 questions - ie all but 2 - AND get them all correct!
To achieve a score of 90 on a 30-question test, you need to answer at least 27 questions correctly, as 90% of 30 is 27. This means you can miss up to 3 questions. Therefore, you can miss a maximum of 3 questions to still score 90.
Provided that all the ones that you do not miss are correct, then 30% of 90 = 90*30/100 = 27.
You can miss out 5 but then need to get all the rest correct. Also, this only works in the scoring system does not penalise wrong answers.
To achieve an 82% score on a 150-question exam, you need to answer at least 123 questions correctly (0.82 x 150 = 123). Therefore, you can get a maximum of 27 questions wrong (150 - 123 = 27).
If you answered 27 correctly and 18 incorrectly, you would have answered 60% correctly.
Around 67.5% which in most school classes would be worth a D+.
