Given: n, number of bags, is more than 5
(1) A total of 24 magnets, 36 postcards, 48 bookmarks, and 60 keychains were packed.
Here we know that GCD is 12, so the maximum number of bags that the items can be distributed in is 12.
But we do not want maximum number of bags, we want number of bags, which can be any factor of (24,36,48,60) which is more than 5
So it could be 6 bags or 12 bags.
6 bags - 4 magnets, 6 postcards, 8 bookmarks and 10 keychains in each bag
12 bags - 2 magnets, 3 postcards, 4 bookmarks and 5 keychains in each bag
We have no way to know if it is 12 bags or 6 bags. Statement 1 is not sufficient
(2) Each gift bag contained magnets, postcards, bookmarks, and keychains in the ratio 2:3:4:5, respectively.
Here again we do not have enough information to confirm number of bags
It could be any number of bags more than 5
6 bags with the ratio 2:3:4:5, means there could be 12 magnets, 18 postcards, 24 bookmarks, 30 keychains
7 bags with the ratio 2:3:4:5 means there could be 14 magnets, 21 postcards, 28 bookmarks, 35 keychains
We do not have the exact number of each item, only the ratio, so this information is not sufficient.
Statement 2 is not sufficient
1 and 2 together
The example we saw earlier of 6 and 12 bags can be used here again
6 bags - 4 magnets, 6 postcards, 8 bookmarks and 10 keychains in each bag >> final ratio is 2:3:4:5
12 bags - 2 magnets, 3 postcards, 4 bookmarks and 5 keychains in each bag >> final ratio is 2:3:4:5
We cannot confirm whether there are 6 or 12 bags.
Answer is E - both together are also not sufficient
