Question: The existing amoutn of water in reservoir = ? Statement 1 : Water in reservoir = Capacity - 430 KL Capacity of reservoir is unknown hence NOT SUFFICIENT Statement 2 : The reservoir is normally 65 percent full. We don't know 65% amounts to how many KL hence NOT SUFFICIENT Combining the statements 100% Capacity - 430 KL = 65% capacity 35% Capacity = 430 KL i.e 65% Capacity = 798 KL SUFFICIENT Answer: Option C Since I am not convinced with use of word 'Normally' in question so I find the language requires improvement in this question and in present condition this question maynot be a good fit for GMAT like practice Related Video: https://www.youtube.com/watch?v=5y7JBioEb8s Like and Subscribe to YouTube channel | access 1100+ more FREE videos | Every subscription matters!!!

Find: kiloliters of water are in a reservoir

(1) If the reservoir were filled to capacity, there would be 430 more kiloliters in the reservoir.
Capacity= x+430 
Not sufficient

(2) The reservoir is normally 65 percent full.
Clearly not sufficient

Both (1)&(2) 
100% Capacity= x+430 
65% of Capacity= x 
35% of Capacity= 430 kl 
So 65% kl water is in the reservoir= 798 kl 
Sufficent

Answer: C

ManifestDreamMBA · Answer

Language is ambiguous and answer can be C or E based on how it is interpreted

Let Capacity of water in kL be W

Statement 1
Let current capacity be x
x+430 = W
Since we don't know x, we cannot find W
Insufficient

Statement 2
Reservoir is normally filled to 65% doesn't tell me W
Insufficient

Combined, I don't know what x is. Cases:
1. If we assume x is normal capacity of 65%, then answer will be C, as the capacity W can be found using 35% of W = 430. On exam I would go with C though, as I believe GMAT won't trick on Quant DS like this
2. If we assume x is still unknown, because we don't know if x is normal capacity or some water has been taken out of it. Then answer is E, because we still don't know x to solve for W

can anyone pls post the OE and the final answer

Harshita2003 · Answer

I think the answer would be E since we do not really have any idea if the water in the reservoir is at normal capacity or not.
