How many can I get wrong on a 50 question quiz to get a 60% result?

Question

So the exam has 50 questions and each is worth 1 point. So how many can I get wrong but still pass (with a 60%)

Answer 1

50 x .6 = 20

haha I would say 20

Answer 2

20 wrong questions and you will still pass.

30/50 = 60%

That means you would have 20 wrong.

Answer 3

Two wrong answers already. Its;

x/50=.6 or 50*.6=30

The answer is 30
