If tank X contains only gasoline, how many kiloliters of gasoline are in tank X.

(1) If 1/2 of the gasoline in tank X were pumped out, the tank would be filled to 1/3 of its capacity.

The values given are % of the total capacity and NO numeric value is given so insufficient
If \(\frac{1}{2}\) is pumped out, HALF will remain so \(\frac{1}{2} = \frac{1}{3}- of -Total\)
so present volume is \(2*\frac{1}{3} = \frac{2}{3}\)
but no numeric value
insuff

(2) If .75 kiloliter of gasoline were pumped into tank X, it would be filled to capacity.
nothing on present status..
we can say present = total - 0.75
insuff

combined
present volume = \(\frac{2}{3}\) of total capacity = \(\frac{2T}{3}\), which is 0.75 less than total
\(2\frac{T}{3} = T-0.75..............\frac{T}{3}=0.75................t=3*0.75\)
suff
