That will depend on the points awarded to each question.
You cannot know that. If you are told the total number of points for the test, you know (or count) the number of questions and you are told that each question is worth the same number of points then, and only then, each question is worth (total points/number of questions) points.
16.5% for each error
Different tests have different rules.
It depends on how many points each question is worth. If they are worth 1 point, 30, 2 points, 15, etc...
2.381 points each
IF the test totals up to 100 points, AND IF every question carriesthe same score, then each question gets 22/9 points.
If the test is worth 100 points, each question would be worth approximately 2.86 points.
As many points as the person who designed the test wants. And they need not be the same for each question, either.
That will depend on the points awarded to each question.
1 since you can only get a 100 on a test
If all the questions are worth the same and the whole test is 100 points, then each question is worth 12.5 points
It depends how many points each question is worth. If each question is worth five points on a twenty question test, you would get ninety-five percent.
1 per question.
You cannot know that. If you are told the total number of points for the test, you know (or count) the number of questions and you are told that each question is worth the same number of points then, and only then, each question is worth (total points/number of questions) points.
Making the totally unjustified and quite possibly unlikely assumption that all questions are worth the same number of marks, each question would be worth 1/18 of the total number of points.
100/150 = 2/3 a point for each question
