If you miss 28 questions out of 70, your score would be 60%
To achieve an 80 percent score on a 75-question test, you need to answer at least 60 questions correctly (since 80% of 75 is 60). This means you can get a maximum of 15 questions wrong (75 total questions - 60 correct answers = 15 wrong).
To achieve an 87 percent score on a 125-question test, you need to correctly answer 87 percent of the questions. This means you need to answer 109 questions correctly (0.87 x 125 = 108.75, rounded up). Therefore, you can get 16 questions wrong (125 - 109 = 16).

45.4545.. % wrong.
30/100*25 =7.5 so you must not get more than 7 questions wrong to score 70%
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.
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.
Your score would be 90.91%
In order to score 80% on a test with 30 questions, you must give 6 wrong answers. You can do it!

To achieve an 80% score on a 55-question test, you would need to answer 44 questions correctly (55 questions x 0.80 = 44 questions). To find out how many questions you can get wrong, subtract the number of correct answers from the total number of questions: 55 total questions - 44 correct answers = 11 questions wrong. Therefore, you can get 11 questions wrong on a 55-question test and still achieve an 80% score.

You can get 60 questions wrong and get a 70 percent but if you get 61 wrong you are at a 69.5 percent.
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!
