You can get 60 questions wrong, which leaves you with 140 answers correct, giving you 70%.
x/30 = .87 x = 26 questions
138 correct answers. 138/150=92
80%=80/100 80/100 x 50 questions = 40 correct answers. therefore 50 - 40 = 10 incorrect answers.
If there are 85 questions, a passing grade of 80% would be 68 correct answers.
Assuming that you get all your answers correct (can you rely on that?), you can miss 12.
16 of them.
You can miss out 12 but: you must get all the remaining correct and there must be no penalties for wrong answers.
If all questions are weighted the same, then you could miss 17 questions, or 26/43 correct, and get a 60 % assuming that there are no penalties for wrong answers.
24 wrong answers
10 questions
If you miss 6 questions you will get an 85% on a 40 question test. To calculate various test score questions, simply divide the number of correct answers by the number of total questions. For example, on your particular question, if you divide 34 (the number of correct answers) by 40 (the total number of test questions), the answer is .85, or 85%.
