5 of them.
You can miss 15 but then must get every one correct.
If you miss 5 out of 15 questions, you have answered 10 questions correctly. To calculate your score as a percentage, divide the number of correct answers (10) by the total questions (15) and then multiply by 100. This results in a score of approximately 66.67%.
To pass a 60-question test with a score of 75%, you need to correctly answer at least 45 questions. This means you can miss a maximum of 15 questions (60 total questions - 45 correct answers = 15 missed questions) and still achieve a passing score.
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
not more than 15
If you miss 5 questions on a 20-question test, you answered 15 questions correctly. To find your grade, divide the number of correct answers (15) by the total number of questions (20) and then multiply by 100 to get a percentage. This results in a grade of 75%.
No more than 15.But why miss any ?
Making the very unlikely assumption that all the ones you do answer are correct and that there are no penalty points for incorrect answers, 52*30% = 15.6 so you can miss out at most 15 questions.Making the very unlikely assumption that all the ones you do answer are correct and that there are no penalty points for incorrect answers, 52*30% = 15.6 so you can miss out at most 15 questions.Making the very unlikely assumption that all the ones you do answer are correct and that there are no penalty points for incorrect answers, 52*30% = 15.6 so you can miss out at most 15 questions.Making the very unlikely assumption that all the ones you do answer are correct and that there are no penalty points for incorrect answers, 52*30% = 15.6 so you can miss out at most 15 questions.
There are 20 questions in total and you are allowed to miss 5 questions at most. I suggest skipping questions you don't know and then answer them later if you can't answer 15 correct.
