You can't get exactly 70 percent, because that would be 11.1 questions wrong out of 37. If you miss 11 or fewer questions your score will be above 70%; if you miss 12 or more questions your score will be below 70%. This assumes the test is more or less "straight"; if it's scored like, say, the SAT (where leaving a question blank does not reduce your score by as much as answering incorrectly) then we'd need to know the exact details of how the test is scored.
24 wrong answers
15 wrong
80% of 80 is 64 64 right answers right and 16 wrong answers
95% of the questions, provided there are no penalties for wrong answers.

80%=80/100 80/100 x 50 questions = 40 correct answers. therefore 50 - 40 = 10 incorrect answers.
You can get 20 questions wrong.
You can get 60 questions wrong and get a 70 percent but if you get 61 wrong you are at a 69.5 percent.
Each question is worth 2.5 percent. You can get 8 wrong.
If you get 7 wrong you'll get 23/30 = 76.66... % Not enough. So fewer than 7. But that is provided that wrong answers score 0 and do not have penalties.
