If you have 20 questions and you get 3 wrong, that means you answered 17 questions correctly. Your score would be 17 out of 20. This can be expressed as a percentage by calculating (17/20) * 100, which equals 85%.
If you scored 85 and got 3 questions wrong, it means you answered 85% of the questions correctly. Let’s denote the total number of questions as (x). Since you got 3 questions wrong, you answered (x - 3) questions correctly. The equation is ((x - 3) / x = 0.85). Solving this, we find that (x = 20). Thus, there were 20 questions on the test.
To calculate the grade, divide the number of correct answers by the total number of questions: (20 - 3 = 17) correct answers. Then, calculate the percentage: (\frac{17}{20} \times 100 = 85%). Therefore, getting 3 questions wrong out of 20 results in a grade of 85%.
If a student gets 3 questions wrong on a 20-question test, they answered 17 questions correctly. To calculate the grade, divide the number of correct answers (17) by the total number of questions (20) and then multiply by 100 to get a percentage. This results in a grade of 85%.
75% right, 25% wrong.
If you get 8 out of 20 questions wrong, you have answered 12 questions correctly. To find your score as a percentage, you can divide the number of correct answers (12) by the total number of questions (20) and then multiply by 100, resulting in a score of 60%.
