Your score is 73.33%
You can only miss 16 points on a 100 point test in order to get an 84%. If the questions are worth 2 points EACH, you can miss 8. If the questions are worth 4 points each, you can only miss 4 questions.
To get seventy percent or better on a quiz of 16 questions one needs 11.2 answers correctly answered. So it is best not to miss 4 but definitely not to miss 5 or more. This answer is arrived at by taking the 16 questions and multiplying by .70 (70 percent) or 16 x .70 = 11.2.
If you got 16 questions correct on a test, and got 80 percent, then there are a total of 16 / (80/100) = 16/0.8 = 20 questions on the test.
If you need 75% to past a test of 16 questions, you need to get at least 12 or more right...
Providing that all 14 remaining questions were correct then the percentage is 87.5%
At most 16 questions. Percent means "out of 100" → 85% of 108 = 85/100 × 108 = 91 4/5 Which means unless you get 92 you will not get at least 85 % Therefore you can miss out on 108 - 92 = 16 questions at most and still get at least 85 %
80% of 81 is 64.8. If you can get partial credit on questions, as some teachers and professors give, you must get at least 4/5 of the possible points on a 65th question, basically. Short of that, you need to answer 65 of the questions correctly, so you can only miss 16.
16/24 x 100 = 66.6 recurring (that is, 66.6666...) percent. That means you got a solid (D) on the test.
16 %
16 correct out of 20 questions is 80%
The answer to this comes from a process called subtraction which most people learn in their first year of school. There were 25 questions and you got 16 right, so what is left over? 25-16=9. Clearly it was not a math test or you would not have done so well.
If all the questions were worth the same amount and 100 percent was a perfect score, then each question would be worth five points and getting seven wrong would get you a 65. Since you got a 64, there must be some scoring information that you neglected to tell us.
