Gasoline Problem (Posted on 2003-04-11) Difficulty: 3 of 5
A man's car runs out of gasoline. His car tank holds exactly 13 gallons. He has three empty unmarked containers which can hold 3 gallons, 6 gallons, and 11 gallons. Using only these containers at the gas station, how can the man bring back exactly 13 gallons?

(He is not allowed to buy over 13 gallons and dispose of the extra.)

I see how you are thinking, but it is kind of complicated. Try using, um, simpler equations. I can tell you for a fact that all you need for this one is addition and subtraction. This really is an easy problem. I see no reason for such complications.

*sigh*  Am I the only one in the world with any common sense anymore?
