You have 2 containers each 1/2 full containing the same volume of water with the same concentration of colouring. One liquid is blue, the other green.
You have a measuring cup which is smaller than the volume of liquid in each container. You take a cup full out of the green liquid container and pour it into the blue liquid container (there is no overflow or spillage). You give it a good stirring. You then take a cup full of the liquid (now mostly blue with a bit of green) - same volume as you previously transferred - from the blue container and pour it into the green container.
The question is, which container now has the greater concentration of original colourant in it? Green, blue, or both the same?

Answer: The container with the blue liquid, of course, . . or if you want a more thorough/comprehensive answer, it's the one you neglected to mention, . . which is the one containing yellow liquid, . . which was mixed with the blue liquid, to make the green liquid. Sorry about that, . . try coming up with something a bit more taxing !

I was told ..... but I have no idea if it is correct or not.....
Originally easter eggs were hard boiled eggs (which as a child we called paste eggs but only at Easter, the rest of the time they were just hard boiled) which you decorated. On Easter Sunday you rolled them down a hill to symbolise the rolling of the blocking stone from in front of the tomb (the decoration was so you knew your own egg which you would eat afterwards .... hoping it didn't encounter dog poo on the way down)

It is suggested it is pagan in origin, but adopted by christianity, as are many 'festivals'. Death and resurrection are themes of pagan beliefs, pre dating many religious doctrines, and eggs are clear symbols of birth. The easter bunny connection is linked to the hare, and early beliefs that they laid eggs (ground nesting birds confusing the issue). All intetesting stuff, but in truth I believe no one categorically knows Rog

Does anyone else want to give an answer? If not I'll post it on CWDF to get some more interest.

The question is, which container now has the greater concentration of original colourant in it? Green, blue, or both the same? Both the same. If "x" equals the volume of the measuring cup and "y" equals the volume of green transferred back from the blue, then each container contains (x-y) of the opposing colour. Even simpler, each container ends up with the same volume as it started with. Therefore there is as much green in the blue as blue in the green.

The question is, which container now has the greater concentration of original colourant in it? Green, blue, or both the same? The green container would have less original, because you have taken a cup of 'pure green' and poured back in a cup which is less than 'pure green'. You have taken a whole cup of pure green out of the green container, but not taken a whole cup of blue out of the blue container, therefore the green container has less of the original.

They will contain the same amounts. I can just about recall this puzzle from school. Canβt remember the maths behind it though...Think we did it with something other than coloured mixtures, coffee and water maybe. Itβs just so long agoπ
