A thoroughly mixed beverage consists only of certain amounts of cream and coffee. What is the ratio of milliliters of cream to milliliters of coffee in the beverage?
(1) Exactly 5 milliliters of cream is contained in 30 milliliters of the beverage.
(2) Exactly 35 milliliters of coffee is contained in 42 milliliters of the beverage.
Remember that you’re only trying to determine if the information is sufficient, so don’t waste time actually trying to find the ratio! You can find the ratio between ingredients once you know the amount of each in the beverage or if you know the amount of one in relation to the a set amount of the beverage (one part to one part in a two part ratio, or one part to whole in a two part ratio).
Using either statement, you can figure out the amount of coffee and the amount of cream for a given amount of beverage (you just need to subtract). The correct answer is D.
