The wording above does not convey a logical meaning. When each serves as an adverb, it cannot refer to a singular noun such as a group. When each serves as an adverb, it may refer only to a PLURAL noun. The prompt seems intended to convey the following: BTGmoderatorDC wrote: A network of car dealerships has d sales directors, each of whom manages a team of a sales associates. In a given month, if the directors each sold 10 cars and each sales associate sold 20 cars, and all cars were sold by either a sales director or a sales associate, how many people in total sold cars? (1) The total number of cars sold was 270 (2) a > d > 2 Since each of the d sales directors manages a sales associates, the total number of sales associates = d*a = ad. Since each of the d directors sells 10 cars, and each of the ad sales associates sells 20 cars, we get : 10d + 20ad = total number of cars. Statement 1: 10d + 20ad = 270 d + 2ad = 27 d(1 + 2a) = 27 The resulting equation indicates that d must be a FACTOR OF 27. Case 1: d=1, with the result that 1+2a=27 and that a=13 In this case, d+a = 1+13 = 14. Case 2: d=3, with the result that 1+2a = 9 and that a=4 In this case, d+a = 3+4 = 7. Since d+a can be different values, INSUFFICIENT. Statement 2: Clearly INSUFFICIENT. Statements combined: Of the various combinations for d and a that satisfy d(1+2a)=27, only the combination in Case 2 satisfies the condition that a>d>2. In Case 2, d+a = 7. SUFFICIENT. The correct answer is C. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.
