8. The correct answer is (A). What you need to know to answer the question is,

essentially, how many cookies can be made per a given unit of butter or, conversely, how

much butter per cookie is needed. Statement (1) essentially provides this information. It

tells you that

5

3

cup butter is needed for 30 cookies; from this information, you can easily

calculate the number of cookies per

2

3

cup—which answers the question. You could

simply set up the following proportion, then solve for B (batch size in terms of number

of cookies):

B

As you can plainly see without doing the math, you can solve for B and therefore answer

the question. Just for the record, B

12. (That’s the answer to the question.) Statement

(2) alone tells us nothing we did not already know; it merely says that tripling the

desired output is achieved by tripling the quantity of each ingredient; that is, 3
