If tank x contains only gasoline, how many kiloliters of gasoline are in tank x?
(1) if 1/2 of the gas in tank x were pumped out, the tank would be filled to 1/3 of its capacity
(2) if .75 kiloliter of gas were pumped into tank x, it would be filled to capacity
Appreciate the help!
Lets say The total capacity of the tank = T
Current amount of gasoline in the tank = CQuestion asks the value of CStatement 1
- if 1/2 of the gas in tank x were pumped out, the tank would be filled to 1/3 of its capacity
C - (1/2)C = (1/3)T
Value of T is unknown. Thus insufficientStatement 2
- if .75 kiloliter of gas were pumped into tank x, it would be filled to capacity
C + 0.75 = T
C= T - 0.75
Value of T is unknown. Thus insufficientStatement 1 & 2
C= (2/3)T -----(Statement 1)
C= T - 0.75 -----(Statement 2)
(2/3)T = T - 0.75
(1/3) T = 0.75
T = 3 * 0.75 = 2.25
Value of T is 2.25 and thus we can calculate the value of C as well. Thus Sufficient
So the answer is C
Hope this detailed explanation helps.
