To achieve a score of 95 percent on a 100-question test, you can get a maximum of 5 questions wrong. This means you must answer at least 95 questions correctly, as 95 out of 100 equals 95 percent.
To achieve a score of 75 percent on a 15-question test, you can get a maximum of 3 questions wrong. This is because getting 75 percent means answering 75 percent of the questions correctly, which equates to answering 11.25 questions correctly. Since you can't answer a fraction of a question, you need to answer at least 12 questions correctly, allowing for 3 incorrect answers.
10 can be wrong and 30 right; 30/40 = 75%
You can get 20 questions wrong.
To achieve an 80 percent score on a 75-question test, you need to correctly answer at least 60 questions. This means you can get a maximum of 15 questions wrong (75 total questions - 60 correct answers = 15 wrong answers).
To achieve 80 percent on a 40-question test, you need to answer at least 32 questions correctly (80% of 40 is 32). This means you can only get 8 questions wrong (40 - 32 = 8). Therefore, to score 80 percent, you can afford to miss a maximum of 8 questions.
