Data Sufficiency

Marcia's bucket can hold a maximum of how many liters of water?

1) The bucket currently contains 9 liters of water

2) If 3 litters of water are added to the bucket when it is half full of water, the amount of water in the bucket will increase by 1/3.


so...

1) Not Unique

Because the volume of water is 9 litters, meanwhile, we still dont know the capacity of the bucket. 9 litters can reach up to the buckets edge, or 9 litters is a half volume of bucket.

2) Ok..seriously...where did the 4/3 came from? I went through the OG explanation..and all i can think is which one comes first egg or chicken?

"If 3 litters of water are added to the bucket when it is half full of water"
------> translate ----> 3 + 1/2(V)

"the amount of water in the bucket will increase by 1/3"
-------------> translate--------> does it mean, (3 +1/2(v)) +2/3 = 1/3 +2/3 ????

Frustrated to the max...
