(3/4)(x+4) C. 3(4x+4) D. 3(x+4) E. 4(3x+4) One-fourth of the people rise up in the air If 1/4 of the x people are in the AIR, the remaining 3/4 of the x people are on the GROUND So, (3/4)x = number of people on the GROUND After a while, 3 of them come back down. So, the number of people on the GROUND is increased by 3 So, now (3/4)x + 3 = number of people on the GROUND Check the answer choices . . . not there! Or so it seems. If we take answer choice B, (3/4)(x+4), and expand it, we get: (3/4)x + 3 PERFECT!

(3/4)(x+4) C. 3(4x+4) D. 3(x+4) E. 4(3x+4) Let x=12. Since 1/4 of the people rise up, the number who rise up = (1/4)(12) = 3. Since 3 people come back down, EVERYONE who rises up comes back down, with the result that all 12 people are practicing yoga on the ground. How many people are now practicing yoga on the ground? The correct answer must yield 12 when x=12. Only B works: (3/4)(12+4) = (3/4)(16) = 3*4 = 12. The correct answer is B. _________________ 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.
