Posted from my mobile device To maximize the number of complete sets in the bag, we should minimize the number of disks selected from each color. Since we are choosing 6 disks and since there are 4 available colors, we should select 2 disks of the same color for 2 colors and 1 disk of each of the remaining colors. If we removed, for instance, 2 green, 2 blue, 1 orange, and 1 purple disks, the remaining disks would be: 10 green, 10 blue, 11 orange, and 11 purple disks, from which we could make 10 complete sets. Answer: E

Since we have 12 discs in each set and 4 colors and we want the greatest number of sets to be remained in the bag after removing 6, we assume that all removed are of different color, 1 disc of each color and 2 of any other but not the same. we will be left with 10 complete sets (+2 discs of some other colors).

E. 10 Must take away at least 2 from 3 colors.

In order to solve this problem we must think about how to maximize the number of complete sets of disks that will remain in the bag. If all 6 disks removed are orange, then there will only be 6 orange disks remaining in the bag. Since there will be 12 blue disks, 12 orange disks, and 12 purple disks remaining in the bag, it will only be possible to select 6 complete sets of disks. So to maximize the number of complete sets remaining in the bag, we should remove a complete set consisting of one green disk, one blue disk, one orange disk, and one purple disk, and then 2 more disks that are of different colors. This will leave 10 complete sets of disks in the bag. There will also be 2 additional different disks. Therefore choice (E) is the correct answer. Posted from my mobile device

Total number of disks 48
Total number of sets 12
Each set has 4 disks
So 4 disks taken from one set, and 2 more from the second set
So we are left with 10 remaining complete sets
YAY
