You would need to answer 68 questions correctly.
60 percent = 60/100 60% of 40 = 60/100 x 40 = 24. Ans: 24 questions.
You can miss out 12 but: you must get all the remaining correct and there must be no penalties for wrong answers.
30/100*25 =7.5 so you must not get more than 7 questions wrong to score 70%
-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
Oh, dude, you're really stressing about this, huh? Well, technically, if you want a 70 percent on a 70-question test, you can get 21 questions wrong. But like, who's counting, right? Just do your best and hope for a generous curve!
If there are 85 questions, a passing grade of 80% would be 68 correct answers.
We must answer 3 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.

Because you must ask the right questions =)
90% of 27 = 27*90/100 = 24.3 So you MUST answer 25 questions - ie all but 2 - AND get them all correct!
