A store selld newspaper A at price of $1 and B at price of $1.25. In a certain day, if r percent of the total income is from A, and p percent of the total copies sold are A, in terms of r, p=?

A store selld newspaper A at price of $1 and B at price of $1.25. In a certain day, if r percent of the total income is from A, and p percent of the total copies sold are A, in terms of r, p=?

x-number to total copies sold

income from A = Qty of A* 1,

r/100* x (1+1.25) = p/100*x*1

income from A in terms of r = Income from A in terms of p

DeeptiM: Please take care while posting question. This question looks as if you have formatted it in your own words; the options are also missing. Please mention the source of the question.

A's revenue: p*1=p B's revenue: (100-p)*1.25=125-1.25p Total revenue=p+125-1.25p=125-0.25p

We know, A's revenue is r% of the total revenue

\(\frac{p}{125-0.25p}=\frac{r}{100}\)

OR

\(r=\frac{100p}{125-0.25p}\)

Likewise, please solve to get p in terms of r. This looks time consuming to me.

Hi Fluke, Thanks a lot for the help.

I have posted the question in exactly similar terms in which it was presented to me..with no options however, the answer you derived is exactly what i have..

The question is from one of my practice set.

Really!!! My bad then. This really sounded strange!! Good that the answer matched luckily and it helped. thanks for posting.

I didn't get it. P is the percent copies .... To find the A' and B' income, why u multiple "p"? shouldn't we multiple the real numbers, not percent, of copies sold?

Hi Fluke Could you please explain it in detail.. Please elaborate your answer..

Which part you didn't understand?

p percent of total copies sold were "A". If p=20%, then B must have sold 80% i.e. (100-p)%

If A sold p percent; B must have sold (100-p)%.

Now, let's suppose the number of copies sold be 100.

A sold = p B sold = 100-p

Money collected from A's sale=p*($1)=p Money collected from B's sale=(100-p)*($1.25)=125-1.25p Total income=p+125-1.25p=125-0.25p

Now, In a certain day, if r percent of the total income is from A;
