you can get 6 wrong. and you will have a 91% if u get more than that then u will be at an 89% (if the ?'s are not all worth the same amount u can get up to 6.5 wrong)
toget 80% you need .8 x 15 = 12 questions right. That means you can 15-12 = 3 questions wrong
Oh, dude, if 80 percent of the questions were answered correctly, that means 20 percent were wrong. So, if 5 questions were missed, that's 20 percent of the total questions. To find out how many questions were answered correctly, you just need to calculate 80 percent of the total questions. Math, man, it's like magic but with numbers.
You need to get 40*60/100 = 24 correct, so you can get 40-24 = 16 wrong.
8 wrong i.e. 32 right 10% of 40 is 4 80% = 8 x 4 = 32 40 - 32 = 8
to get a 90 you need to answer 56 questions right (6 wrong) to get an 80 you need to answer 50 right (12 wrong) to get a 70 you need to answer 44 questions right (18 wrong) to get a 60 you need to answer 38 questions right (24 wrong)
Oh, dude, you're hitting me with some math here. So, to get 80 percent on 75 questions, you'd need to get 60 questions right. That means you can get 15 questions wrong and still hit that 80 percent mark. So, like, you've got a little wiggle room there, but don't push it too far!
To achieve an 80% score on a 55-question test, you would need to answer 44 questions correctly (55 questions x 0.80 = 44 questions). To find out how many questions you can get wrong, subtract the number of correct answers from the total number of questions: 55 total questions - 44 correct answers = 11 questions wrong. Therefore, you can get 11 questions wrong on a 55-question test and still achieve an 80% score.
To pass the test you need 70% of the questions right.
60
You would need to answer 68 questions correctly.
You need to divide 3 / 14, then multiply the result by 100 to get percent. That gives you the percentage of wrong answers.Note that if you want the percentage of RIGHT answers, divide 11 / 14, then multiply by 100 to get percent.
