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.
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.
0.70 x 125 = 88 questions right You can miss 125-88 = 37 questions to get 70 percent But you got to get all the rest correct!

138 questions right and 12 questions wrong
I took a test that had 35 questions. I got a 91%, how many did I miss?

Getting 72 per cent right means if you had 100 questions you would have got 72 correct. Since there were half as many questions (50), you would have got half as many (36) correct.
