This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

10 reduced by 5 is $10-5=5$

Let's say you want to reduce 40% of L by 20% of it , $\frac{40L}{100}-\dfrac{20L}{100} = \frac{20L}{100}$

Btw , I am guessing you didn't actually mean asking these questions , did you ? So please refrain from asking such questions .

Sorry it was worded in a lame manner Consider that the chance of a person watching a particular arbitrary show is 40%.Now that chance is reduced by 20% because of some reason. See it could be as you said become 40% - 20% = 20%. (or) 40 - 40*(20)/(100)= 32% Hence it is ambiguous right. Do you agree wid me

You see what I had posted was : reducing 40% of L by 20% of L .

Let 40% of L be x . Now what you are asking is x reduced by 20% of x . Which gives :

$x - x \frac{20}{100} = x \frac{4}{5} = \frac{4}{5} \cdot \frac{40}{100} L = \frac{8}{25} L$

So I guess we were talking about two entirely diff. things . But yeah , if the sentence is not read properly , it could certainly lead to errors !

Do you mind if I ask you why did you post this note ? Did you look up some Survey or something of the sort ?
