Three containers have capacities of three five and nine liters How can these containers be used to measure exactly seven liters of water?
Several ways to achieve this - here is one solution. Fill the 5 litre container and pour it all into the 9 litre container. Fill the 5 litre container and pour it into the 9 litre container until the latter is full - leaving 1 litre in the 5 litre container. Empty the 9 litre container. Fill the 3 litre container and empty into 9 litre container. Repeat. There are now 6 litres in the 9 litre container. Pour the 1 litre from the 5 litre container into the 9 litre container which now contains 7 litres.
How do you measure 4 liters of water if you have a 7-liter and a 5-liter bucket?
This method works with any such problem, as long as the two buckets' liter-capacities (or gallon capacities, etc.) have no common factors, or else the common factors are also factors of the amount you're trying to measure. Fill the 7-liter bucket, and empty 5 liters of it into the 5-liter bucket; then dump out the 5 liters. Two liters will remain in the 7-liter bucket; transfer them to the 5-liter bucket. Fill the 7-liter bucket again, and empty enough of the bucket into the 5-liter bucket to fill it. That should only be 3 liters transfered, leaving 4 liters left in the 7-liter bucket. QED.
We have three jars one of 12-liter one 7-liter and one 5-liter. The 12-liter jar is full of water and the 7-liter with the 5-liter jar are empty. How do you get 6 liters of water using the two jars?

The 5-liter jar is empty, as of now.2)Transfer 5 liters from the 7-liter jar into the 5-liter jar.The 12-liter, 7-liter, 5-liter jars now contain 5, 2 and 5 liters respectively.3)Empty the contents of the 5-liter jar into the 12-liter jar.The 12, 7, 5- liter jars now contain 10, 2 and 0 liters respectively.4)From the 7-liter jar, take out 5 liters and pour 7 liters from the 12-liter jar into the 7-liter jar.We now have 3 liters in the 12-liter jar and 7 in the 7-liter one, while the 5-liter jar has only two liters in it.5)Fill up the remainder of the 5-liter jar using the 7-liter jar.That leaves us with 3 liters on the 12-liter jar and 4 liters in the 7-liter jar. The 5-liter jar is full.6)Pour the contents of the 5-liter jar into the 12-liter jar.There are 8 liters in the 12-liter jar and 4 liters in the 7-liter jar, while the 5-liter jar is empty.7)Pour the 4 liters that are in the 7-liter jar into the 5-liter jar.We now have 8 liters in the 12-liter jar and 4 liters in the 5-liter jar. The 7-liter jar is empty.8)Fill the 7-liter jar using the 12-liter jar.There is now only 1 liter in the 12-liter jar and 7 liters in the 7-liter jar and 4 liters in the 5-liter jar.9)Fill up the 5-liter jar using the 7-liter jar.There is now 1 liter in the 12-liter jar and 6 liters in the 7-liter jar and 5 in the 5-liter jar.NOTE: This might not be the only way, or the shortest way to do it.

If you have to measure exactly 4 liters of water but you only have a 3-liter bottle and a 5-liter bottle How do you do it?
Fill the 3-liter bottle to the top, then pour the water into the 5-liter bottle. Refill the 3-liter bottle again and pour water into the 5-liter bottle until it's full. This leaves exactly 1 liter in the 3-liter bottle. Empty the 5-liter bottle, then pour the remaining 1 liter from the 3-liter bottle into the 5-liter bottle. Fill the 3-liter bottle once more and pour it into the 5-liter bottle, making a total of 4 liters.

How do you precisely measure 4 liters of water if you only have one 3 liter bucket and one 5 liter bucket with a steady flow of water?
== == == == Fill the 3l and dump into 5l. Fill 3l again pour into 5l til full, you now have 1l left in 3 l container. dump 5 onto ground, pour the 1l from the 3l container into the 5l, then fill 3l and dump into the 5l....Presto exactly 4 liters are contained in the 5l container. ALTERNATIVELY (i) Fill the 5l and then fill 3l from 5l. This leaves 2l in the 5l. (ii) Empty 3l (iii) Pour the 2l from the 5l into the 3l. This leaves 1l of spare capacity in the 3l. (iv) Fill the 5l again (v) Fill the 3l from the 5l. This leaves 4l in the 5l.ALTERNATE 2:If flow is steady, time may be used to help. Take amount of time it takes to fill 5 liter bucket, divide by 5 then multiply by 4. Answer will be how long you must let the water flow into the 5 liter bucket to fill it upto 4 liters.
