(1) If 1/2 of the gasoline in tank X were pumped out, the tank would be filled to 1/3 of its capacity.
(2) If .75 kiloliter of gasoline were pumped into tank X, it would be filled to capacity.
Let G = the gas in the tank and C = the capacity of the tank.
Statement 1:
G - (1/2)G = (1/3)C
No way to solve for G.
INSUFFICENT.
Statement 2:
G + 0.75 = C
No way to solve for G.
INSUFFICIENT.
Statements combined:
Since we have two variables (G and C) and two distinct linear equations with these variables (see above), we can solve for the two variables.
Thus, the value of G can be determined.
SUFFICIENT.
The correct answer is
C.
