Hint : Since each question is worth the same, the number of questions you need to get correct doesn't depend on the marks that each question is worth.

mathmale · Answer

Try this approach:  Let x=the number of questions you have to get correct to pass.
Then solve the following equation for x:
$$\frac{ x }{ 27 }=0.80$$\]

You pass if you have x questions (or more) correct.
