Bris Vegas Posted October 8, 2012 Share Posted October 8, 2012 That took me 10 seconds to figure out and I hadn't read any of the previous quotes.. OK, next question.. You have a 3 litre jug and a 5 litre jug.. You need exactly 4 litres in total and you can't spill any.. How do you do it.. (you have unlimited water) Link to comment Share on other sites More sharing options...
ladyram Posted October 8, 2012 Share Posted October 8, 2012 2.. It's easy, you have 9 tins.. Weigh 3 on each side, which is 6 (and leaves 3)... If one side is heavier, it leaves 3.. If not, it's one of the remaining 3.. Then weigh 2 of the 3.. (one on each side and the other tin left off) If one tin is heavier the scale will show, if not then it's the remaining tin you have left on the side.. It isn't easy. Behave.

davenportram Posted October 8, 2012 Author Share Posted October 8, 2012 Ooops thought it was a single scale... Yeah, if you weigh two, if they balance then you have the heaviest can spare. If not then the heaviest is one of those, so you swap one for the other of the three The lollipop goes to BondJovi Weighing 1 : 3 tins in each side. If one side drops then the heavy can I'd one if those three. If they balance then it is in one of the three not on the scale Weighing 2 : once you have the three tins that contains the tin identified weigh any two of them. If these balance it's the tin not in the scales. If one side drops then that is the heavier tin. Link to comment Share on other sites More sharing options...

davenportram Posted October 8, 2012 Author Share Posted October 8, 2012 Fill the five litre jug then pour it into the three litre jug. Empty the three litre jug Pour the two litres left in the 5 litre jug into the three litre jug Then refill the 5 litre jug and pour one litre into the other jug to make it up to 3 litres - leaving 4 litres in the 5 litre jug Link to comment Share on other sites More sharing options...
