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

Well, darling, to get an 80 percent on a 70-question test, you can afford to get 14 questions wrong. As long as you nail the rest of those questions, you'll be golden. Just remember, it's not about how many you get wrong, it's about how many you get right.
It depends how many points each question is worth. If each question is worth five points on a twenty question test, you would get ninety-five percent.
40-26=14 questions answered correctly. 14/40=.35 Therefore the percentage of the test would be 35%
