x/30 = 0.93
x = 28 questions
x/30 = .87 x = 26 questions
You can get 20 questions wrong.
five
100 divided by 5 is 20. 100 minus 20 is 80. The answer is 1.
As 11.2 is 80% of 14, you would have to get at least 12 questions right to be above 80%, so you could only get 2 questions wrong.
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.
24 wrong answers
10 questions
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.
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!
