27 * 81/100 = 22 problems correct -> 5 problems incorrect.
To find the total number of problems on the test, we can set up the equation based on the percentage score. If 12 problems correct correspond to an 80% score, we can express this as: ( 0.80 \times \text{total problems} = 12 ). Solving for total problems, we get: ( \text{total problems} = \frac{12}{0.80} = 15 ). Therefore, there are 15 problems on the test.
You might not have missed any - you just got nearly half of them wrong.
I took a test that had 35 questions. I got a 91%, how many did I miss?
25%
10% so you got a 90% on the test
7/60 = 0.11(6), so 7 is about 12% of 60. You would have an 88% on that test.
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.
well i got 6 wrong out of 30 and i failed so im guessig its 6
If every question was worth the same credit, you missed 18 of them.
83. You may have typed the question wrong.
To calculate the number of correct answers you got on a test, you can use the formula: (score / total possible score) x total number of questions. In this case, you got a score of 78 on a 65-question test. So, (78 / 100) x 65 = 50.7. Therefore, you got approximately 51 questions correct on the test.
My guess is that it wasn't a maths test. 32 X 0.82=26.24 so you missed 6. Your teacher gave you an extra mark as that comes to 81%.
