A museum gift shop packed a number of souvenir items: magnets, postcards, bookmarks, and keychains into identical gift bags for visitors. If more than 5 gift bags were packed, how many gift bags were packed?
(1) A total of 24 magnets, 36 postcards, 48 bookmarks, and 60 keychains were packed.
(2) Each gift bag contained magnets, postcards, bookmarks, and keychains in the ratio 2:3:4:5, respectively.
Gift bags = n
n > 5
Each bag has identical gifts
(1) A total of 24 magnets, 36 postcards, 48 bookmarks, and 60 keychains were packed.
If I have to put each item in uniform numbers in each bag then I need
HCF (24, 36, 48, 60) = 12
Hence, 'n' can be 1, 2, 3, 4, 6, 12 bags
Now n> 5 hence n can only be 6 or 12
Insufficient
(2) Each gift bag contained magnets, postcards, bookmarks, and keychains in the ratio 2:3:4:5, respectively.
magnets = 2n, postcards = 3n, bookmarks = 4n, and keychains = 5n
No limit to the number of bags that can be created with this
Insufficient
Combining 1 and 2 we get
If total magnets = 24 and
2n = 24 => n = 12
Hence the number of bags is 12
