On Halloween, Céilidh distributed candy to the trick-or-treaters who came to the door, with each trick-or-treater receiving exactly x chocolates, y gummy bears, and z lollipops. How many trick-or-treaters came to Céilidh's door?
(1) The numbers of chocolates, gummy bears, and lollipops that each trick-or-treater received were in the ratio 3:4:5, respectively.
(2) Céilidh distributed a total of 24 chocolates, 32 gummy bears, and 40 lollipops.

I think I got why it is E..
On Halloween, Céilidh distributed candy to the trick-or-treaters who came to the door, with each trick-or-treater receiving exactly x chocolates, y gummy bears, and z lollipops. How many trick-or-treaters came to Céilidh's door?
Let's say that the number of trick or treaters that came to the door is A
That would mean that we have...
\(Ax + Ay + Az\)
equalling the number of candies handed out in total. That's about all we know for now.
(1) The numbers of chocolates, gummy bears, and lollipops that each trick-or-treater received were in the ratio 3:4:5, respectively.
Just knowing the ratio of candies does not tell us the values of x, y, z, or A.
insufficient
(2) Céilidh distributed a total of 24 chocolates, 32 gummy bears, and 40 lollipops.
This means that Ax = 24, Ay = 32, and Az = 40.
Unfortunately, this still does not tell us anything about the exact number A.
In some ways, 1 and 2 are telling us the same exact thing..
insufficient
(1) & (2):
Although the total candies in 2 are distributed with the same ratio noted in 1, this gives us no specific value for the constant A.
A can be any common factor between 24, 32, and 40 (2, 4, 8) and still hold the same ratio.
insufficient E

What is the source? This is a near-exact copy of an OG question:
https://gmatclub.com/forum/a-department ... 04852.html
Anyway, the answer is E because there could be one person receiving 24, 32 and 40 of each candy, or there could be eight people receiving 3, 4 and 5 of each, among other possibilities.
