GMAT QUESTION(Can someone explain)

The answer cannot be B, as per me it should be C since we should know the current quantity of water in the bucket while soving the second part of the question.

Thanks

As per q : we need to know the max. amt. of water...

From 1: we know it holds 9 ltrs of water but it never says it is the max. amt. insufficient.

From 2 : x/2+3=x/2+x/3 (assuming x the max. amt of water)
=>x=9 so sufficient.

'B' should be the ans.

(although stem 1 it says the bucket currently holds 9 ltrs of water, it never says that this the max amt of water)

Hi Amit,

The answer should be B. However, I would like to point out an error in your equation.

Statement 2 says "will increase by 1/3". 1/3 here is relative to half the capacity, and NOT the full capacity.

So your equation should indeed be: 3 = (x/2)*(1/3), and you will arrive at x = 18 litres, which is the capacity of the bucket.

Hope this is clear.

I agree...
