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 . Azhaghu Roopesh M · 2 years ago

@Azhaghu Roopesh M 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 Selena Miller · 2 years ago

@Selena Miller 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 ? Azhaghu Roopesh M · 2 years ago
