Answer:

24 questions

Step-by-step explanation:

Given

[tex]Score = 75\%[/tex]

[tex]Correct\ Questions = 18[/tex]

Required

Determine the number of question

Represent this with n.

Since each question has 1 point each, then

[tex]Score * Number\ of\ questions = Correct\ Questions[/tex]

Substitute values for Score, Number of Questions and Correct Questions

[tex]75\% * n = 18[/tex]

Make n the subject.

[tex]n = \frac{18}{75\%}[/tex]

Convert percent to decimals

[tex]n = \frac{18}{.75}[/tex]

[tex]n = 24[/tex]

Hence, there are 24 questions in total
