A hiker in a national forest stopped at a ranger station to add water to her canteen. How many ounces of water were in the canteen when she arrived at the ranger station?

(1) The hiker added 24 ounces to the canteen at the ranger station.
(2) After the hiker added water to the canteen, the canteen was 75 percent full.


from 1) we just know how much was added

from 2) we dont know how much was added in x = 3/4 C

Combination
24 + x = 3/4C

2 unknowns, 1 equation

E

The answer is option E (none of the statement).

First of all, we do not know how much water was left in her canteen when she reached the station.

Now according to statement 1, she added 24 ounces of water. But we do not know how much (in terms of volume) was her canteen full. This is being told in statement 2 that she got her canteen full till 75 percent. But we are missing a vital piece of information here. What if, already her canteen was 50% filled when she got it refilled? And what if her canteen was completely empty when she reached the station? In both cases, the answer will be different hence both the statements are insufficient.
