Out of gas. (Posted on 2007-09-22) Difficulty: 2 of 5
A man runs his car out of gas thereby completely emptying his 16 gallon tank. He only has a 3, a 6, and a 11 gallon container (and fortunately a wagon to carry the containers in) in his trunk. He has nothing else in which he can carry gas. He walks a few miles to a gas station, and as luck would have it the gauge on the pump is broken so he can not use that to measure the fuel. He is in a pretty remote area with only one gas station for miles. Gas costs $3.099, and he only has a $50. Using only the containers provided, and only walking once to and from the gas station, how can he get exactly 16 gallons of gas into his car?

I could agree with the first solution, although it is not my intended solution.  Knowing he is the only gas station for miles, the clerk could be a(n) &*%^ and just say to fill it up as much as you can afford or find another gas station.  We could pretty well guess 5/6 of a container too, but the question does say exactly 16 gallons in his car.

As far as the second solution. I would like to know a gas station which would give you extra gas without paying for it, and allow you to give back a gallon. What are they going to do pour it back into the nozzle and hope it flows to the tank? Sorry, no offense meant, but I think this solution is crap.
