(2) C paid a total of \$16 to A and B for his share.

So we need to calculate the price of each beer bottle,considering they consumed equal quantities and the price per bottle was same.

Statement 1:

The statement simply status the number of beer bottles brought.
No information about whether they consumed all bottles of beer or not.Also no information about the price of
each bottle.

Statement 2"

The statement means that A paid \$16 for his share but we dont know how many bottles he consumed.

Combing equation 1 and 2,

We still dont know how many bottles have been consumed,we just know the number of bottles that were brought.
So Insufficient.

My answer would be E for this.Waiting for OA to be posted

Press Kudos if it helps !!

I think there is assumption in the question then between bringing bottles and consuming bottles..

In that case since its not explicitly stated in the question I would discard this question on quality issues.

The point is: they brought different quantities of beers, but drank them equally and thus must pay equally. it asks uf for the price

1) total beers = 12. how much is one? insufficient
2) C owes 16\$ to A and B. It means that right now A and B had paid exactly 8\$ more than what they were supposed to. but how much is one Beer ? it could be 4\$ or 2% or 1 \$. How many beers there were ? it could be 16, 8, 4 or anything. INSUFFICIENT
1+2) total beers = 12
C owes 16\$ thus 8\$ to A and 8\$ to B.
so 12 = A+B+C
total cost = X(A+B+C) = X(12)
single expenditure = X(12)/3 = 4X
but A and B spent 4X + 8 each
while C spent 16 ( the exact money he owes and thus that everyone owes) thus,
4x = 16
x=4
total expenditure = 48
single expenditure = 16
