If there are 85 questions, a passing grade of 80% would be 68 correct answers.
90% of 27 = 27*90/100 = 24.3 So you MUST answer 25 questions - ie all but 2 - AND get them all correct!
100 - 69 = 31, and it's percent, so it's .31 .31*30 = 9.3, but you must round down or up (down to get more than 69%), so you can miss 9 questions and still fail.
50 gallons @ 3% must be added.
9.7% because you must move the decimal to places to the right. NEVER say it's 97%!
The minimum number you must answer correctly is(0.01) x (the percentage needed to pass) x (the number of questions on the test).
You would need to answer 68 questions correctly.
We must answer 3 questions.
To score 70% or higher you must get at least 70/100 * 70 = 49 questions right. So you can get 70 - 49 = 21 questions wrong, but no more!
28
60 percent = 60/100 60% of 40 = 60/100 x 40 = 24. Ans: 24 questions.
Each question is worth 2.5% so lets say the fail is 60%, you have to get 24 questions right to get a 60%, for an A you have to get 36 questions right.
You can miss out 12 but: you must get all the remaining correct and there must be no penalties for wrong answers.
You must get 19 questions right on a 25 question test to earn a score of 75%
30/100*25 =7.5 so you must not get more than 7 questions wrong to score 70%
35 out of 40.
-a 6/8 is a 75% -a 7/8 is an 87% So in order to get at least an 80%, you must score at least a 7
Because you must ask the right questions =)
