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 liters 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
My answer is coming 9 lts however the answer given is 18 lts. What fail to understand is when the increase in level of bucket is due to the water added then why 3 = 1 /3x wrong.

Statement 1 is clearly insufficient: the current volume tells us nothing about the capacity of the bucket.[email protected] wrote:Marcia's bucket can hold a maximum of how many

My answer is coming 9 lts however the answer given is 18 lts. What fail to understand is when the increase in level of bucket is due to the water added then why 3 = 1 /3x wrong.
Statement 2 implies that the 3 liters being added are equal to 1/3 of the water in the bucket:
3 = (1/3)w
w = 9.
Since the bucket contains 9 liters and is half-full, the capacity of the bucket is 18 liters.
SUFFICIENT.
The correct answer is B.

Statement 1 - Not Sufficient - No information is provided regarding the maximum capacity of the bucket.
Statement 2
Let the bucket capacity = x
According to the question,
Bucket is half full = x/2 (Given)
Adding 3 liters of water = x/2 + 3
Now,
Bucket is half full + 3 liters of water added = Amount of water in the bucket will increase by 1/3 (Note: Initial amount of water in the bucket is x/2: Given)
Hint - (1/3 increase of the original value => 4/3 of the original value)
x/2+3=x/2*4/3
solve for x, Answer = 18 - "SUFFICIENT"
Key here is to break down the statements step by step.

(1) The bucket currently contains 9 liters of water but we do not know the maximum volume of bucket; NOT sufficient.[email protected] wrote:Marcia's bucket can hold a maximum of how many

Let V be the total volume of the bucket.
Then volume of water in the bucket when it is half full = V/2
When 3 liters of water are added to the bucket, it's current volume = (V/2) +3 = [V/2 * 1/3] + (V/2)
Now we can find the value of V; SUFFICIENT.
The correct answer is B.
