Question

Jasmine has taken an online boating safety course and is now completing her end-of-course exam. As she answers each question, the progress bar at the bottom of the screen shows what ponion of the test she has finished. She has just completed Question 12, and the progress bar shows she is 20% complete. How many total questions are on the test?

​

Answer 1

There are 60 total questions on the course exam.

Explanation:

Given that:

Number of questions finished by Jasmine = 12

Percentage shown on the bar = 20%

The total number of questions will be 100%, therefore, 20% of the questions are equal to 12.

Let,

x be the total number of questions on the course exam

20% of x = 12

`(20)/(100)x=12\\0.2x=12`

Dividing both sides by 0.2

`(0.2x)/(0.2)=(12)/(0.2)\\x=60`

Hence,

There are 60 total questions on the course exam.
