if you get 22 questions wrong, you will have a 78%. less then 22 wrong would mean a higher percentage and more then 22 wrong would mean a lower percentage.
22 questions can be wrong. This means that you would have to get 33 marks, which is 60%
getting 6 wrong means you have 22 correct so you do 22/28= 0.78 (rounded) this timesed by 100=78%
100*4/22 = 18.1818... (recurring) % wrong.

It is: 22/57 times 100 = 38.6% rounded to one decimal place

22 of them for a 75% pass rate providing that the remaining 66 questions are all correct
So basically there was a test with 72 questions and you got x number of them wrong, and got 70%. So... You have to find out what 70% of 72 is. All you have to do is multiply 0.70 by 72. Which equals 50.4 50 represents the number of questions you got right out of 72. So, 50/72 = roughly 70% -------------------------------------------------------------------------------------------------- 72 - 50 = 22 SO. To answer you question, you can miss 22 questions out of 72 to get 70 percent. Why does it sound like you're trying to go all lazy on a test?
You can get at most 22 questions wrong, otherwise you will score less than 70 %. To get 70% right you can get 100 % - 70 % = 30 % wrong 30% of 75 = 30/100 x 75 = 22.5 I assume you can't get 1/2 a question wrong, so you can get at most 22 questions wrong otherwise you will score less than 70 %.
It depends but it will probably be a D- or a F
70% of 31 questions is 31*70/100 = 21.7 questions. However, since you cannot have 0.7 questions, the answer is one of: 21 questions = 68% or 22 questions = 71%
