All of them - you'd fail, but the question did not say anything about passing the test!
To determine the number of questions you can miss out of 42 questions, you need to know the passing score or the minimum number of correct answers required. Without this information, it is not possible to specify the number of questions you can miss.
The answer depends on how many of the ones that you do are correct and whether there are any penalties for wrong answers.
well you can go to answer right under ask and it will give you a list you can answers
30/100*25 =7.5 so you must not get more than 7 questions wrong to score 70%

you can only miss10 questions WRONG
It depends on the state and how many questions there are on the test. Call the DMV and ask, or check the drivers manual; it should tell you what passing is
If you miss 10 questions, you will get a 60%. This is usually the lowest passing score.

If you get 7 wrong you'll get 23/30 = 76.66... % Not enough. So fewer than 7. But that is provided that wrong answers score 0 and do not have penalties.
In order to score exactly 70% on a test with exactly 70 questions ... if every questionis worth the same credit ... you have to get 21answers wrong. You can do it.

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 %.
To score 70% or higher you must get at least 70/100 * 70 = 49 questions right. So you can get 70 - 49 = 21 questions wrong, but no more!
Answer 34 questions correctly, ignore the rest.
