Example 4

How did you figure out that the total was 8 when 3/4 of 6 is 2? I may be writing this all wrong. Doing the math, 3/4 of 6 is 4.5. I know that you were just punching in numbers, yet this was difficult to grasp.

Hi @Vanessa-Ratcliff,

I agree this question is a little bit confusing!

In the video, Mehran just chose numbers that were easy to work with to help visualize the problem.

We know that the number of manuscripts approved by each censor was the same. Here, Mehran chose 6 as the number of manuscripts approved by each censor.

We know that the number of manuscripts approved by the first censor was 1/2 of the total number of manuscripts submitted. So, if 6 were approved, then 6 must not have been approved.

We know that the number of manuscripts approved by the second censor was 3/4 of the total number of manuscripts submitted. So, if 6 were approved, then 6 is equal to 3/4 of the total submissions:

3/4 = 6/x

3/4 = 6/8

6 is 3/4 of 8, so the total number of manuscripts submitted under the second censor was 8 and the number that were not approved would be 2 which is 1/4 not 8.

Don't stress about this too much! As long as you understand why the answer is correct based on the placeholder numbers that Mehran provided you are good to go!

Hope this is helpful! Please let us know if you have any further questions.

Thanks,
Is it normal to find Must Be True questions EXTREMELY difficult? They are not as concrete as previous LR lessons; the set-ups are murder!
