93.85% (61/65,*100)
You'd be 100% right.
-- Since she answered 86 percent of the questions correctly, she answered the remaining 14 percent of them incorrectly. -- 14% of 100 questions is 14 questions.
19/20 as a percentage = 100*19/20 = 95%
You can get 20 questions wrong.
30
20
100 divided by 5 is 20. 100 minus 20 is 80. The answer is 1.
17 percent wrong, 83 percent right.
You can get at most 20% wrong. 20% of 16 is 16*20/100 = 3.2 Since you cannot get 0.2 questions wrong, the maximum possible is 3 questions.
30/100*25 =7.5 so you must not get more than 7 questions wrong to score 70%
if you get 22 questions wrong, you will have a 78%. less then 22 wrong would mean a higher percentage and more then 22 wrong would mean a lower percentage.
100/9 = 11.11 %
The answer depends on whether or not there are penalties (negative marks) for wrong answers. If not, then the answer is 30.
100*4/22 = 18.1818... (recurring) % wrong.
10 is the answer,because 100 - 80 = 20 divide that by 2 and you get the answer. 50 - 40 = 10
