Step-by-step explanation:
Hello,
I don't think I have found it. But I want to be notified by the answer, so I will only post my reasoning. I will go for E.
The stem gives us this information:
x(10) + y(r) = 12 (x+y) --> just diretly moved x+y from the denominator so it is easier to read.
On the side, this also tells us that x+y are multiples of 12, even though I wasn't able to use this anywhere..
[1] Based on the first stem, we know that the heavier pumpkins are 5 more than the lighter ones, h = l+5.
However, we don't know if r>10 or r<10. It cannot be 10 because then there wouldn't be any heavier pumkins. So, NS.
[2] Says that the weight of the heavier pumkins is 3 more than their number.
We still don't know if r is more or less than 10 and we also don't know x and y (so the number of each type of pumkins). So, NS.
[1,2] Tell us thatt the weight of the heavier pumkins is l+5+3=l+8.
What I did then is replace x+y with l+h, because it is basically the same. So, this gives:
x+y = l+h = (l+5)(l+8)+l(r).
However, we still don't know if x or y are the heavier ones. So, in the end we still end up with r, y, x and l to solve for. So, NS.
So, I think we need to know something more to solve it.
