I love fantasies, brain teasers, word puzzles, IQ tests and mindfuck through optical illusions. I find that gnawing on my brain is ridiculous. Not that I am busy with this all day, but just, just in between I think it's super. From those questions or riddles that settle in your head, until you have the right answer. Or just be amazed by the mindfuck of your brain. I find it not only fun but also very instructive.
When I discover these new calendars at Deltas, I can not make a choice. I like them all !! So I ask them all. And now my desk is full. But it is fun !! These calendars have one disadvantage, of course, they lead off horribly. Because one riddle or optical illusion per day, definitely ask for more ... and the chances are that I arrived in December already in December and the site here is flattened because I am busy with discovering and riddling.
Riddles with answers
Of course, with the riddles, the redemptive answer and with the optical illusions you find out what happens in your brain. I am amazed. It makes me happy. But let me not anticipate things and discuss the calendars one by one:

There are 360 bottles of wine in a cellar:
90 bottles of white wine
120 bottles of red wine
150 bottles of rosé
What is the percentage of white wine? What is the percentage of red wine? Solve this without pen and paper.
3/12 - 4/12 - 5/12
Solution example 2
90: 360×100 = 25
25% of the bottles are white wine
120: 360 x 100 = 33
33% of the bottles in red wine
I used a different calculation myself (outcomes are the same however). It occurred to me that all numbers were divisible by 30, with the addition sum (360) divisible by 12 to arrive at that 30. So assuming 360 12/12 is then:
90 white bottles = 3/12 (ie 1/4, so 25%)
120 red bottles = 4/12 (so 1/3, so 33%)
150 rosé = 5/12
Actually, I found my solution much easier ...! And the results are the same, so both calculations are correct. It does not matter how you come to the right solution, if you let that brain crack!
