Answer 1

24 questions

Explanation:

Given

`Score = 75\%`

`Correct\ Questions = 18`

Required

Determine the number of question

Represent this with n.

Since each question has 1 point each, then

`Score * Number\ of\ questions = Correct\ Questions`

Substitute values for Score, Number of Questions and Correct Questions

`75\% * n = 18`

Make n the subject.

`n = (18)/(75\%)`

Convert percent to decimals

`n = (18)/(.75)`

`n = 24`

Hence, there are 24 questions in total
