How many pets does the office manager have? # of pets # of employees 0 --------------2 1---------------3 2--------------2 3--------------3 A. 3 B. 4 C. 5 D. 6 E. 7 List of 10 pet values implied by the chart: 0, 0, 1, 1, 1, 2, 2, 3, 3, 3 Since the answer choices are all 3 or greater, the addition of the manager's pet value will yield the following list of 11 values: 0, 0, 1, 1, 1, 2, 2, 3, 3, 3, M Since the new average must be equal to the median value in blue, the sum of the 11 values = (count)(average) = 11*2 = 22. Thus: 0+0+1+1+1+2+2+3+3+3+M = 22 16+M = 22 M = 6 The correct answer is D. _________________ 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.

How many pets does the office manager have? # of pets # of employees 0 --------------2 1---------------3 2--------------2 3--------------3 A. 3 B. 4 C. 5 D. 6 E. 7 OA=D Source: Magoosh Let x = the number of pets the manager has. If x is 1 or less, then the median is 1. If x is 2 or more, then the median is 2. From the given choices, we can expect that x is 2 or more, therefore, we have: (0 * 2 + 1 * 3 + 2 * 2 + 3 * 3 + x)/11 = 2 16 + x = 22 x = 6 Answer: D _________________ Scott Woodbury-Stewart Founder and CEO scott@targettestprep.com See why Target Test Prep is rated 5 out of 5 stars on BEAT the GMAT.
