Answer 1

Answer:

24 questions

Step-by-step 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.

$n = \frac{18}{75\%}$

Convert percent to decimals

$n = \frac{18}{.75}$

$n = 24$

Hence, there are 24 questions in total
