40% were wrong.
7 wrong out of 22 questions = 31.8% wrong. 15 correct out of 22 questions = 68.2% correct. I hope it wasn't a math test.
To achieve an 80 percent score on a 75-question test, you need to answer at least 60 questions correctly (since 80% of 75 is 60). This means you can get a maximum of 15 questions wrong (75 total questions - 60 correct answers = 15 wrong).
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.
To achieve a score of 70 percent on a 50-question test, a student must answer at least 35 questions correctly (70% of 50). This means they can get a maximum of 15 questions wrong (50 - 35 = 15) and still meet the passing criteria.
toget 80% you need .8 x 15 = 12 questions right. That means you can 15-12 = 3 questions wrong
40 percent wrong questions. To calculate the percentage 6 divided by 15 and multiplied by 100.
Oh, dude, you're hitting me with some math here. So, to get 80 percent on 75 questions, you'd need to get 60 questions right. That means you can get 15 questions wrong and still hit that 80 percent mark. So, like, you've got a little wiggle room there, but don't push it too far!
73 questions on the test, all worth the same credit. Score 79% means you got -- 58 correct (79.452%) -- 15 wrong (20.548%)
70% of 15 is 10.5 so it is 4.5 questions
