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 answered 23 questions incorrectly.

You got 89 percent. Hence, you answered 89/100*150 = 133.5 questions. hence you missed 150 - 133.5 = 16.5 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.

70 PER CENT means 70 out of a hundred... so you missed 30

If every question was worth the same credit, you missed 18 of them.
