.8 x 30 = 24 so you can miss 6 questions
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.
