It can be 100 or 50 questions.
if you get 22 questions wrong, you will have a 78%. less then 22 wrong would mean a higher percentage and more then 22 wrong would mean a lower percentage.
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.
22 questions can be wrong. This means that you would have to get 33 marks, which is 60%
You can get up to 150 questions wrong.

It is not possible to say. You could have missed none but got a whole lot wrong!

As 11.2 is 80% of 14, you would have to get at least 12 questions right to be above 80%, so you could only get 2 questions wrong.
When I graded papers, no matter how many questions, I would mark the questions wrong that were wrong with checks. Then, to come up with a grade I would subtract the number possible with the number wrong. That would give me the total number right and from that you assign a grade to the paper.

You can get 63 questions wrong and get 70%.
3/50 = 0,06 = 6 percent wrong, which means you get 100 - 6 = 94 % correct answers. Also it depends on how many you got wrong, so if you got 5 wrong you would get an 84.
