I took a test that had 35 questions. I got a 91%, how many did I miss?
If all 35 questions were worth the same credit and you got a 75 percent,then you put down the wrong answer for 83/4 questions.
You might not have missed any - you just got nearly half of them wrong.
That is an A. You got 19 out of 20.
If you missed out 11 AND got all the rest correct you would have 83.08%. However, if you miss out 11 out of 65 it is unlikely that you are good enough to get all the rest correct!
You can't get 90% in a test with 32 questions. However, if calculated the answer would be 3.2. i.e., you would miss 3.2 questions to get 90%. This can happen when the examiner gives you marks even for a partially correct answer.
It is not possible to say. You could have missed none but got a whole lot wrong!
You got 89 percent. Hence, you answered 89/100*150 = 133.5 questions. hence you missed 150 - 133.5 = 16.5 questions.
