8 out of 15 is less than 55%
30/100*25 =7.5 so you must not get more than 7 questions wrong to score 70%
76.67%
41 questions (if you got 83 percent, then that means you got 34 questions right)
Assuming that all questions score equally, you can miss out at most 7. And then need to get them all correct.
Even if you assume the questions are all worth the same number of marks, the answer may well depend on the grade boundaries.
You are in the C-D range. If you had missed 7 out of 15 that would be a solid D. You can do better I don't know you but I know you can do better.

76.67%
41 questions (if you got 83 percent, then that means you got 34 questions right)
The percentage is 68/75 times 100/1 = 90.'6'% recurring '6'
Assuming that all questions score equally, you can miss out at most 7. And then need to get them all correct.
the answer is suck my toe
You take the total number of missed problems, subtract from total of questions, divide by total of questions (then convert to percentage). Example: 10 total questions on test, three are missed Step 1: 10 - 3 = 7 Step 2: 7 divided by 10 = .70 Step 3: .70 converted to percentage = 70%
Even if you assume the questions are all worth the same number of marks, the answer may well depend on the grade boundaries.
93 % A+.Since it is 93% so anything higher than 90% will be counted as a A+.
7 wrong out of 22 questions = 31.8% wrong. 15 correct out of 22 questions = 68.2% correct. I hope it wasn't a math test.
