D

Since afterwards we 13 ppl so 33*1+13*1=46

I dont feel this question is correct but still go with D

The question is not clear.
But... as per statements...
x= number of people
y= every one drank that many bottles
so,, xy=33
Also, next day..
13 people are present.
they drank.. y/3
so they drank.. 13* y/3

Summing 1 and 2,
33+ 13*y/3..
so..value of y can in 3,6...
if we look at the option..the only value it satisfies is.. y=3, and total number of people is 46.. D is the best choice

So... the nonl

I also got D with a similar approach:

If n - number of people at the party at the first day, then 33/n - amount of vodka drunk by 1 attendee.
The next day people drand 3 times less, so 1 attendee drank (33/n)/3=11/n.
As there were 13 ppl present the next day, they drand 11/n*13.
11 and 13 are prime numbers, so n can be equal either to 11 or to 13, then the amount of vodka drunk the next day will be either 13 or 11 respectively.
33+13=46
33+11=44 (there is no answer like that, although there is a an explanation of why this answer is not suitable).

Let no of people in the party = x

Day 1 = guys drank 33 bottles, equally. Now, we dont know how many people we at the party? They could have drank half a bottle, each or a full bottle...66 or 33 # of people, respectively.

Day 2 = 13 people present. Rest of the bottles?? dont know. Actually, we dont know the total # of bottles?

I'm not able to go beyond this :s
