Some people get stumped by the triangles hiding inside of the triangles and others forget to include the giant triangle housing all of the others. Either way, very few individuals—even math teachers—have been able to find the correct answer to this problem. And for more questions that will put your former education to the test, check out these 30 Questions You’d Need to Ace to Pass 6th Grade Geography.
You might need to ask your kids for help on this one.In order to solve this seemingly simple problem, you need to remove the decimal from 1.92 and act like it isn’t there. Once you’ve divided 192 by 3 to get 64, you can put the decimal place back where it belongs and get your final answer of 0.64.
Since we know that there are two zombies for every three humans and that 2 + 3 = 5, we can divide 85 by 5 to figure out that in total, there are 17 groups of humans and zombies. From there, we can then multiply 17 by 2 and 3 and learn that there are 34 zombies and 51 humans respectively.
As humans, we pride ourselves on our cerebral capabilities. We’re rational, we’re witty, we’re smart … and we’re observant.
The rational brain is so adept at using collected information to form ideas, opinions, and predictions about the world that it can sometimes deceive us. We notice patterns that aren’t there because we expect to see them; we fill in the gaps because we predict the finished picture.
Logic is idealistic. Sometimes, reality isn’t quite so perfect!
Let’s take mathematics as a prime (no pun intended!) example. Math problems (think sudoku) have blasted into orbit in terms of their widespread popularity in recent years. Turn to the back pages of any popular newspaper or magazine and you’ll find word puzzles, math problems, and all manner of tricky brain teasers.
You have to concentrate, because the puzzles are designed to challenge our brains’ propensity to predict conclusions before assessing all the details in the picture. The challenge is often irresistible. One particular test has been circulating the internet. It has taken most viewers a good while to solve it, and some people never did. Are you someone who likes to skip forward to the spoilers or will you put the time in and try to solve this puzzle yourself? Can you see what’s missing in this sequence?
The viral picture shows a sequence of numbers from 1 to 53. We’ll give you a clue: two numbers are missing. How about an added challenge? Okay, you asked for it. Set yourself a 20-second timer!
Give up?
Maybe you proved that you’re smarter than the masses and found the missing numbers immediately. If so, well done you. Bask in well-deserved pride and tell all your friends about it! For the rest of you, here’s the information you’re looking for …
Do we hear groans all round? It’s not as complex as you thought! This puzzle is an excellent example of how our busy brains fill in the gaps before our eyes have truly taken in the information. If you solved the sequencing puzzle, then good for you, smarty-pants. If not, then better luck next time!
Are you a math whizz? Do you enjoy a logical challenge? Share this puzzle with all of the critical thinkers you know!
Do you feel like testing your gray matter with a mind-bending puzzle of logic? If so, then you’ve come to the right place. We have a challenging and fun problem of deduction that will pump some blood to your brain and boost your intellectual efficiency!
Only 37 percent of participants solved it on the first try, so if you like challenges, then this puzzle is for you. You only need elementary logic to solve it, so, in theory, most of us should be able to. We suggest keeping it simple by just using the ol’ pen and paper. You may find that when you write everything down, the solution pops out at you more naturally. Are you ready? Let’s go!
Please look at the diagrams below and follow the instructions:
Please try to solve the puzzle on your own, as there is nothing more satisfying than conquering the difficulties life sets before you. If you tried and failed, then try again. We’re sure you can do it! But if you’re stuck and are ready to throw in the towel to fight another day, then check out the solution below.
Explanation:
Keep in mind our two constraints! The car is in just one box, and also, only one of the three statements is true (which implies that the other two must be false!)
First, let’s assume that the statement under the first box is true. Then, the car is in the first box. And the other two statements must be false; are they? Let’s test and see! If the statement under box 2 is false, then the car is in the box 2, but that is not possible, since the car can be in only one box! Therefore statement 1 must be false, and the car cannot be in box 1.
Now let’s assume that the statement written on the second box is true. Then the car is not in the second box. But, since only one statement can be true, then the other statements must be false! So, let’s test them and see if they are indeed false. Statement 1 says that the car is in box 1, so if this statement is false, then the car must be in box 3. Then, if we test statement 3, which says that the car is not in box 1, well, it cannot be in box 1 as we have just shown. Therefore, statement 2 must be false! … and if statement 2 is false, that means the car must be in box 2!
Now, even though we have found our answer, let’s examine statement 3 for the fun of it. Were we to assume statement 3 is true, then the car cannot be in box 1, and the other two statements must also be false. Statement 1 says the car is in box 1 and that is false—which is what we expect if statement 3 is true. Then statement 2 must also be false, and we come to the same conclusion again! The car must be in box 2!
Did you manage to solve this riddle on your own? If so, then congratulations! If not, then don’t worry, there will be plenty more changes to try your logic skills again! Please share this puzzle with your friends if for no other reason than to keep them on their toes!
How quickly can you spot the T hidden in this collection of Ls?
You might find it quite difficult at first, so we’ll give you a clue… what if we tell you it’s NOT going to be a red letter?
Although this seems like helpful information, scientists have discovered that it can actually slow down your reaction time at first.
In a study by Johns Hopkins University, published by psychologicalscience.org , participants were given one colour to consistently ignore.
But after some practice, taking part in 100 trials, they appeared to have trained their brains and were finding the target letters much faster than those who weren’t given a colour to eliminate.
So the more we practise ‘ignoring’ information, the better we get at focusing on what we’re actually looking for.
Still can’t find it?

The blog Centauro says the puzzle is used in Hong Kong, and it appears on tests for children entering the first grade.
“This was one of the questions that children of the age of 6 faced as part of their entry exam to a primary school in Hong Kong, since this was published on the Chinese social media network Sina Weibo (Chinese twitter), it has been touted as one of the most popular things to come out of China since the invention of fireworks,” it says.
Students have less than 20 seconds to solve it.
You can find the answer below.
Answer: The trick with the puzzle is to flip the image upside down, therefore the answer is 87.
Lately, the internet has been having a lot of fun with “Find the Panda” puzzles.
It started with Hungarian artist Dudolf hiding a panda among some snowman.
The game then got an upgrade when other users hid the panda among metalheads and stormtroopers.
The only problem was that the puzzles were too easy, with many users commenting that it took them less than 10 seconds to find the panda. Some even remarked that they found the panda almost immediately.
Hence Tracy Lynn Heightchew, from Louisville, Kentucky, decided to step up the game. The above picture is an old photo of the National Junior Achievers Conference in 1978; within it, Heightchew has hidden a panda.
If the previous puzzles didn’t test you, this one should be much more satisfactory, with many more users commenting that it took them upwards of 30 seconds.
There are nine balls. One is slightly lighter than the rest; the difference is small enough that you can’t tell just by picking them up. Using a basic two-sided scale, what’s the minimum number of times you’d need to weigh balls to guarantee you find the light one?
This is one of those questions that, allegedly, gets asked in job interviews. I say “allegedly” because I don’t really believe places really give brain teasers. (Although I haven’t had a job interview since 2003, so maybe they’ve changed, man.)
