Question

Jackson answered 3 questions correctly on his multiple choice history final and earned a grade of 5%. How many total questions were on the final exam?

Answer 1

It's 60.

Explanation:

You can think of it like this:

If Jackson got a grade of 5% for 3 questions, then I can continuously multiply by 3 to get to 100.

3 questions is 5%.

6 questions is 10%.

12 questions is 20%.

24 questions is 40%.

48 questions is 80%.

Add another 12 questions for another 20%, and you get 100%.

48 + 12 is 60. 60 is your answer.

I put it this way so that way you can understand the basic concept of percentages.
