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
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)
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.
To get exactly 90% you need to miss 5.6 questions.
You would need to know the number of questions on the test, and then multiply that number by 0.08 to find the number of essay questions.
The test has 25 questions and you can only get 5 questions wrong, if not you fail.You only need to get 15 questions right to pass.
