If r percent of the store’s revenues from newspaper sales was from Newspaper A and if p percent of the newspapers that the store sold were copies of newspaper A, which of the following expresses r in terms of p?

A. 100p / (125 – p)

B. 150p / (250 – p)

C. 300p / (375 – p)

D. 400p / (500 – p)

Answer: d

my answer is:

400p/(500-100p)

I can't find what's wrong with my answer?

Please post youe questions in 涛涛GWD-xx-yy format. Thank you! Not sure if there's a map between the original GWD and 涛涛's version. You can try asking in 走出GMAT困境.

I agree with your answer.
