You would need to answer 68 questions correctly.
68
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!
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.
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%
