Have you ever had the feeling that your child is getting way smarter than you when riddles or homework from his or her school left you stumped and speechless? We have.
Try to solve these four simple puzzles that elementary school children seem to be able to solve in an instant.
Puzzle 1. A parking spot
This simple puzzle was given to first graders in Hong Kong as an entrance exam. Kids cracked it in just a few seconds.
Just turn the picture upside down in your head.
Puzzle 2. The four-digit numbers
Preschoolers can crack this one in five to 10 minutes; educated programmers in an hour!
Answer: 2581 = 2.
Try to count the number of circles in each four-digit number. For example, 6 has one circle, 8 has two of them, and 6889 has six! Got it?
Puzzle 3. A numerical pyramid
Third graders in Singapore solve brain teasers and numerical puzzles like this one in a couple of minutes.
Answer: D = 1345; E = 2440.
The bottom numbers are connected to the upper level. First, add the numbers in the bottom line: 198 + 263 = 461.
Now you see that the number you got is greater than its neighbor above: 461 > 446.
Subtract these numbers: 461 — 446 = 15.
If you check the rest of the pyramid, you’ll get 15 in each case.
Ta-dah! Here’s the key.
Puzzle 4. A box of chocolates
This one is from an American 12-year-old student’s math worksheet.
There are 50 chocolate candies in the box. 30 of them come with caramel filling, 25 with coconut, 10 of them are two-flavored candies with caramel and coconut, and the rest of them are just chocolate candies with no filling.
Question: Which diagram reflects the box of chocolates correctly?
Answer: diagram B.
It’s just some simple math:
How many caramel candies are there in the box? 30 — 10 = 20.
And how many coconut candies are there? 25 — 10 = 15.
Now you can find out how many plain chocolate candies were there in the box! 50 — (20 + 15 +10) = 5.
Puzzle 5. Which way this bus is driving?
The bus us moving to the left because the door is on the other side.
Puzzle 6. How can this be?
To solve this, you’ll need to imagine number 29 in Roman digits. That way, it’ll look like this XXIX. Now you simply remove I, and get XXX, which in Arabic system means 30.
Puzzle 7. The village idiot
Visitors to a scenic mountain village were often amused by the village idiot. When offered a choice between a shiny 50-cent piece and a crumpled $5 bill, he would always happily choose the half-dollar. The bill was worth ten times as much, so why did he never choose it?
The so-called village idiot was smart enough to realize that as long as he kept choosing the 50-cent piece, people would keep offering him the choice. If he once took the $5 bill, the stream of coins would stop rolling in.
