In the standard formulation of a flavored drink the ratio by volume of flavoring to corn syrup to water is 1 : 12 : 30. In the "sport" formulation, the ratio of flavoring to corn syrup is three times as great as in the standard formulation, and the ratio of flavoring to water is half that of the standard formulation. If a large bottle of the "sport" formulation contains 3 ounces of corn syrup, how many ounces of water does it contain?

A. 15
B. 30
C. 45
D. 60
E. 90

Standard: \(\frac{f}{\frac{c}{w}}=\frac{1}{\frac{12}{30}}\);

Sport: "the ratio of flavoring to corn syrup is three times as great as in the standard" --> \(\frac{F}{C}=3\frac{f}{c}=3*\frac{1}{12}=\frac{1}{4}\) and "the ratio of flavoring to water is half that of the standard formulation" --> \(\frac{F}{W}=\frac{1}{2}*\frac{f}{w}=\frac{1}{2}*\frac{1}{30}=\frac{1}{60}\).

So sport: \(\frac{F}{\frac{C}{W}}=\frac{1}{\frac{4}{60}}\). Now, if \(C=4*\frac{3}{4}=3\) ounces then \(W=60*\frac{3}{4}=45\) ounces.

Or: as \(\frac{F}{\frac{C}{W}}=\frac{1}{\frac{4}{60}}\) then \(\frac{C}{W}=\frac{4}{60}=\frac{1}{15}=\frac{3}{45}\), so if \(C=3\) then \(W=45\).

Answer: C.

I also got C
F:C:W
1:12:30

F:C is 3x
3:12

F:W is 1/2
1:60

so...
F=3 (1 * 3)
C=12 (nothing changed)
W=180 (30*=60 for halfing the ratio and then 3*60 to bring it back into the correct ratio with F)

Ratio:
F:C:W
3:12:180

12/4=3oz of C
so...
180/4=45oz of water

so if i've got it right, 1 : 12 : 30 is equal to f/c/w where the ratio of flavoring to water can be literarily written as 1/30 right ?

Yup.
Flavor or Corn Syrup is 1:12

Hi,
is the OA wrong in this question? Shouldn't it be "c" as in Bunuel's solution?
