Brain Teasers are Back!

Good idea !

your 4/4/4 start is good and you do get a lot of useful information from that weighing. And of course, if you are lucky, the next couple of steps follow quite easily, but …

… if you aren’t so lucky, the next two steps take a bit of careful thinking !!

Of course, it’s quite easy to do in four weighings, but then it wouldn’t be such a tease :sunglasses:

I think you could post your response now, unless Eoink considers he is close to a solution ?

Hopefully the response is funny ?

Don is waiting the response. We wait a bit more?

Funny ? More funny to pronounce it quickly and see that people don’t understand nothing,

There is no rush Eoink, I know you are fully engrossed with diamond transactions at the moment. Perhaps another bottle or two of those delicious red wines you enjoy might assist ???

An easier one while sorting out diamonds and French tongue-twisters :sunglasses:

Which diagram is the odd one out, and why ?

A B D are symmetrical, not C.

A to B and D to A. C to anyone.

What is the common link?

I’m struggling to generate “symmetrical” pictures of A, B and D. Perhaps it’s just the choice of words. English has so many words with very similar, but nevertheless different, meanings

Do you perhaps mean “reflection” ?

For example, B is a reflection of A about a line drawn Top to Bottom through the letter B so as to bisect picture B. PowerPoint would refer to this as a “Horizontal Flip”.

The drawing below illustrates what I mean by “reflection”. Is this the same as your “symmetry” ?

Symétrie, as in the pic. Or in mirror.

B is refexion to A , D to B. C to none. It’s that ?

If you mean like the drawing below, then that is a good solution. Nice.

But there is a better solution, in which three of the pictures can be made to look exactly like each other, and the fourth picture can’t, so is the odd one out.

Have you an idea on the common link above ( artistic picture) ?

There seem to be a few “mice” in the picture.

Could be…the response has some physics reasons…

I think it’s time to close out a few of the open Teasers.

Number the diamonds 1 to 12 and divide them into three groups of 4
1,2,3,4 then 5,6,7,8 and 9,10,11,12
Put the first two groups on the balance
IF these two groups balance, the odd diamond is in Group 9,10,11,12

Compare group 1,2,3 (in fact any three diamonds from 1 to 8), with group 9,10,11.
IF group 1,2,3 and 9,10,11 balance, then the odd diamond is No 12

Compare 12 with any diamond to discover whether its heavy or light.

Of course, there are a couple of “IFs” in the scenario above. The second “IF” is quite easy to develop ie IF 1,2,3 and 9,10,11 do NOT balance then …

…well, I’ll leave it there for a while :sunglasses:

The response for the picture of Morgane Tschiember art work: bubbles

Common link: density. ( glass and concrete).

Brain “ phonetic “ teaser: Sisisisisisigarsisansisisisansigar:

Si six scies scient six cigares
Si cent scies scient six cent cigares

If six hand-saws saw six cigars
Six hundred hand-saws saw six hundred cigars

One little, tiny amendment perhaps, but I might be wrong, my French isn’t too strong these days…

…should that second line start “Six cent…” rather than “Si cent…” ???

But a nice teaser nonetheless.
