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%.
60% right, 40% wrong.
As a percentage it is 60% providing that all answered were correct
90% of 20 questions = 90*20/100 questions = 1800/100 = 18 questions.
80% means 80/100 = 0.8 0.8 * 20 = 16 --------------------just multiply 20 by 8 ( = 160 ) and replace the decimal place.
If there are 20 questions then each question is worth 5 points because 100 total points divided by 20 equals 5.If you missed 8 questions then 8 times 5 points equals 40 points wrong, so you have to subtract that from 100 to get a grade of 60. Study harder next time.
20 questions missed out of 140 leaves 85.71%.
