5 children's puzzles, which are not under the power of adults. Turn on the attention, simple logic and childlike. Forward, on Board the ship!

1. Four-digit numbers

Preschoolers know the answer for 5-10 minutes. Programmers – in 1 hour. The majority of people with higher education... Well, check for yourself. And try to be honest, not in a hurry to learn a ready answer (it will be in the end, under all the other jobs).

Little hint: try to think outside the box.





Can not figure out? You have 2 more hints (read first if does not help, then move on to the second).

1) Remember who's the fastest solution to this problem? Preschoolers. Why? Think how they.

2) Think "visually". This is not a mathematical problem.

2. Parking

One basic question – this time from the Hong Kong test for admission in primary school. "Inexperienced" graduates of the kindergarten is given to the solution 20 seconds!





3. Numeric pyramid

Hello again from Singapore. Try to compare in my mind with the local third graders that easily cope with the mathematical problem below. (But if you get stuck, not much worry: as shown TV poll of adults found it "difficult", "too intellectual" and even "insoluble"!)





4. Chocolate box

Now migrated to the USA. Here's one of the tests the usual Washington 7th graders (for the local system is 12-13 years old).

"A box of 50 chocolates. 30 of them with caramel, coconut 25, 10 caramel and coconut and the other without stuffing. Question: Which diagram accurately reflects the contents of the box?"





5. Family ties

And finally a puzzle that is not even related to math. Nevertheless, it is puzzling to many adults, while the children almost instantly give the correct answer!

"Father and son get into a car accident. The father dies on the spot. Son in critical condition was taken to hospital for surgery. The surgeon looks with horror at the child and says: "I can't operate on him! That's my son!"

Question: How is that possible?"

So, attention...

Responses and ways of solutions

1. Four-digit numbers

Should have just mentally rotate the picture upside down.

 

3. Numeric pyramid

Answer: D = 1345; E = 2440

First put the two numbers in the bottom row: 198 + 263 = 461 has received the amount of more than the number that stands above them: 461 > 446 Subtract the smaller from the larger: 461 — 446 = 15

Similarly, consider the rest of the pairs and see that everywhere it turns 15. TA-dam!

Here is the key to the solution.

 

4. Chocolate box

Response: figure B

Simple arithmetic:

How much chocolate after a while? 30 — 10 = 20

How much chocolate only coconut? 25 — 10 = 15

How much is chocolate without filling? 50 — (20 + 15 +10) = 5
