No timer is there as the question has not been posted in correct forum. I will do the needful.

This can have two immediate solutions.

A) Substitute some values for n
Let there be total 100 bottles out of which 20 are A and 80 are B. Thus, n is 20.
Total revenue = 20*10+80*15 = 1400
% from n bottles = \(100*\frac{200}{1400}=\frac{100}{7}\)
ONLY E fits in. => \(\frac{400n}{(600 - 2n)}=\frac{400*20}{600-2*20}=\frac{8000}{560}=\frac{100}{7}\)

B) Algebraic
Let there be 100 bottles, so A is n bottles and B is 100-n bottles
Total Revenue = 10*n+(100-n)*15 = 1500-5n
10n as % of 1500-5n = \(100*\frac{10n}{1500-5n}=\frac{200n}{300-n}\), which is same as E.

I would go with the substitution approach by using smart numbers as m is 50% and n is 10 bottles. starting with the option C. This is enable me to understand if I have to move up or move down in the options order.

BTW,... the answer is E

The wording of the question is confusing and makes little sense but this is what the question is saying:

Last Friday, a grocery store sold only 2 items - wine A bottles ($10 per bottle) and wine B bottles ($15 per bottle)
m% of its Friday's revenue came from wine A and n% of bottles sold were of wine A.
Which of the following represents m in terms of n?

I would take n = 100 (all bottles sold were of wine A only) so m = 100 should be obtained in this case.
Plug n = 100 and only option (E) will give you 100.
