Are YOU smarter than a Hong Kong very first grader? Logic puzzle from Chinese primary school exam stumps adults but 6-year-olds can crack it in just twenty seconds

- The test shows a car parked in a lot with the number of its space obscured
- The reader is then asked to work out the number of the parking space
- Six-year-olds can evidently accomplish the question in twenty seconds
- But for adults – who think it through more – it can leave them stumped
A logic puzzle has baffled the internet, but its solution is evidently so elementary that a child can solve it in seconds.
The now-viral puzzle comes from a Hong Kong elementary school admission test for six-year-olds, who are required to solve it within twenty seconds.
The test, as reported by Centauro, features a drawing of a parking lot with a car placed in one of the six numbered catches sight of, blocking the number from view.
Based on the visible numbers, the students are asked to determine the number of the spot where the car is parked.

If you can’t solve it right away, you’re not alone: evidently, many adults have been stumped by the first-grade entrance exam question.
At very first glance it might seem like logic or algebra is needed to find the right reaction.
But, as it turns out, the solution is much lighter than it very first shows up. It is explained below.
Oldest trick in the book: Slide the blue tab to expose the badly plain solution to the logic problem
The trick is to roll over the page – or the computer screen – with the drawing, making it apparent that the parking catches sight of are numbered in a sequence, from eighty six to 91.
The car is therefore in the second-left space, which is parking spot number 87.
Adults tend to overthink the question, erroneously believing that the solution is rooted in sophisticated mathematics, but children, who have a tendency to look at things from various angles, quickly take hold of the plainness of the puzzle and screw the response right away.
British puzzle inventor David Bodycombe told The Guardian this week that the parking lot logic problem is his brainchild, inspired by a car park he had seen in Portugal twenty years ago.
It goes after a number of other seemingly difficult maths questions that have gone viral lately, including an Edexcel GCSE Maths question in the UK that had some students complaining on Twitter.
THE OTHER MATHS QUESTIONS THAT STUMPED THE WORLD
When is Cheryl’s bday?
In April this year, people across the world were left baffled by a maths problem set for 14-year-olds in Singapore.
Albert and Bernard just became friends with Cheryl, and they want to know when her bday is. Cheryl gives them a list of ten possible dates.
May 15, May 16, May Nineteen
June 17, June Eighteen
July 14, July 16
August 14, August 15, August 17
Cheryl then tells Albert and Bernard separately the month and the day of her bday respectively.
Albert: I don’t know when Cheryl’s bday is, but I know that Bernard does not know too.
Bernard: At very first I don’t know when Cheryl’s bday is, but I know now.
Albert: Then I also know when Cheryl’s bday is.
So when is Cheryl’s bday?
The solution is in the picture below.
In June, GCSE students in the UK complained about what they said was a particularly hard Edexcel Maths paper.
There are n sweets in a bag. Six of the sweets are orange. The rest of the sweets are yellow.
Hannah takes a sweet from the bag. She gobbles the sweet. Hannah then takes at random another sweet from the bag. She munches the sweet.
The probability that Hannah slurps two orange sweets is 1/Three.
Showcase that n²-n-90=0
The solution was to work out that it was not asking for the value of n, but to do some algebra to demonstrate that n²-n-90=0.
When Hannah takes her very first sweet from the bag, there is a 6/n chance it is orange.
This is because there are six orange sweets and n sweets in total.
With her 2nd sweet, there is a Five/(n-1) chance that it is orange.
This is because there are only five orange sweets left out of a total of n-1 sweets.
The chance of getting two orange sweets in a row is the very first probability multiplied the 2nd one: 6/n x Five/n–1
The question tells us that the chance of Hannah getting two orange sweets is 1/Three.
So: 6/n x Five/n–1 = 1/Three
Now rearrange this equation.
Then times by three on both sides to cancel out the fraction gives:
