You would need to know the number of questions on the test, and then multiply that number by 0.08 to find the number of essay questions.

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.

30

14 of them.

5

41 questions (if you got 83 percent, then that means you got 34 questions right)

As 11.2 is 80% of 14, you would have to get at least 12 questions right to be above 80%, so you could only get 2 questions wrong.

You would need to answer 68 questions correctly.

Each question is worth 2.5 percent. You can get 8 wrong.

62 questions, you just have to divide 48 by 3 and that is 14 and then you just add 14 to 48.

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

22 questions can be wrong. This means that you would have to get 33 marks, which is 60%

If there are 85 questions, a passing grade of 80% would be 68 correct answers.

At least 11. 30 questions right would be 75% and 29 would be 72.5%, which would round up to 73%.
