A. 0% B. 5% C. 10% D.15% E. 20% OA A Source: Manhattan Prep Letâ€™s let the initial number of candies of each color be 12 (and thus the total number of candies is 60). So he eats all 12 green candies and 6 orange candies at first. Next he eats 3 orange, 6 red, 6 blue and 6 yellow candies. Thus far, we have 60 - (12 + 6 + 3 + 6 x 3) = 60 - 39 = 21 candies left. At this point, there are 3 orange, 6 red, 6 blue and 6 yellow candies left. Since 15% of 60 is 9, he must eat 12 more candies to get to 9. However, since he eats an equal number of of red and yellow candies, he must eat 6 red and 6 yellow candies to have 9 candies left. Therefore, there will be no more red candies left.

A. 0% B. 5% C. 10% D.15% E. 20% Let R=O=G=B=Y=20, for a total of 100 marbles. Kaz eats all of the green candies and half of the orange ones. R=20, O=10, G=0, B=20, Y=20 He eats half of the remaining pieces of each color. R=10, O=5, G=0, B=10, Y=10 He eats red and yellow candies in equal proportions until the total number of remaining candies of all colors equals 15% of the original number. Since only 15 of the original 100 candies must remain, Kaz must eat the 10 remaining red and 10 remaining yellow candies, leaving only O=5 and B=10: R=0, O=5, G=0, B=10, Y=0 What percent of the red candies remain? (new R)/(original R) = 0/20 = 0% The correct answer is A. _________________ 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.
