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. 70

D. 45

E. 90

In standard formulation
F:C:W=1:12:30

in sport, F:C=3:12 or F:C=1:4 and F:W=1:60
so in the "sport" formulation,F:C:W=1:4:60
so if the bottle has 3 unit of C,amount of W = (3/4)*60 =45

Ans option D

[selango]

Standard Formulation:

F:C:W=1:12:30

Sport Formulation:

F:C=3:12=1:4

F:W=1:60

F:C:W=1:4:60

C:W are in 1:15 ratio.

So if there 3 ounces of corn syrup,then there is 45 ounces of water

Answer D
