Starting state of the standard puzzle; a jug filled with 8 units of water, and two empty jugs of sizes 5 and 3. The solver must pour the water so that the first and second jugs both contain 4 units, and the third is empty.
In the wine/water mixing problem, one starts with two barrels, one holding wine and the other an equal volume of water. A cup of wine is taken from the wine barrel and added to the water. A cup of the wine/water mixture is then returned to the wine barrel, so that the volumes in the barrels are again equal.
Changing 1 right cup and 1 wrong cup, the situation remains the same. Changing 2 right cups results in a situation with 3 wrong cups, after which the next move restores the original status of 1 wrong cup. Thus, any number of moves results in a situation either with 3 wrongs or with 1 wrong, and never with 0 wrongs.
But in northern England, a quarter pint could also be called a jack or a noggin, rather than a gill, and in some areas a half-pint could be called a gill, particularly for beer and milk. [2] [3] [4] In Scotland, there were additional sizes: [5] big gill = 1 + 1 ⁄ 2 gills (213.1 mL) wee gill = 3 ⁄ 4 gill (106.5 mL) wee half gill = 3 ⁄ 8 ...

Let x be the new total mass of the potatoes (dry + water). Let d be the dry mass of the potatoes and w, the mass of water within the potatoes. Recall w is 98% of the total mass, that is, w = 0.98x. Therefore, x = d + w = d + 0.98x, i.e., x = d / 0.02 = 50d. In our case, as noted above, d = 1 kg so the new mass of the potatoes will indeed be 50 kg.
As a rule of thumb in US water management, one acre-foot is taken to be the planned annual water usage of a suburban family household. [b] In some areas of the desert Southwest, where water conservation is followed and often enforced, a typical family uses only about 0.25 acre-foot per year (310 m 3 /a) of water per year. [4]
In the U.K., the use of the fluid ounce as a measurement in trade, public health, and public administration was circumscribed to a few specific uses (the labelling of beer, cider, water, lemonade and fruit juice in returnable containers) in 1995, and abolished entirely in 2000, by The Units of Measurement Regulations 1994.
