Brain-splitting equation that even a MATHS TEACHER can't solve

[xunzi]

81 would be technically correct as well but since the 4petal flower can be anything, the answer is infinity.

 

[ConcealCarry]

number of petals has nothing to do with the value, it's the colour.

102

 

[danger007]

right answer is ???? ...

 

[xunzi]

Another variation could be:

Red flower = 20

Blue Flower = 5 = number of petals

Blue flower - 3 = 2 = number of flowers

Problem = 1 + 20 X 4 = 81




Mathematically, it should be 101, and loss of a petal is probably a printing mistake on part of paper setter (since you said that this was for children in school).

If we go by visual logic, then 81 could be an answer or 80 + SQRT(2) could be an answer.

And as @xunzi said, there could be infinite answers.

Beside the 4 petal different from the 5 petal flower. the size is also different, which mean that 4 petal flowers can be any tiny of fraction of the 5 original petal flower so the correct answer is just infinity. It can be anywhere from 80 to 80.999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999

Smart kid!

Elementary enough for kindergarden kids or 5 year old in India?

"Elementary" means something very basic in a particular field. In this case, algebra. It is a very elementary problem in algebra. You are confusing "elementary" with "easy". They are not the same. What is easy for a 10 year old can be difficult for a 5 year old.

Einstein's two postulates are very elementary to special relativity. That doesn't mean that it is easy for a kindergarten student, or for you for that matter.

right answer is ???? ...

∞

That is the best and most legit answer.

 

[danger007]

∞

That is the best and most legit answer.

am using mobile.. infinity not available..

And as @xunzi said, there could be infinite answers. If it is not 101, then infinite makes much sense as petal logic fails in case of Red flower.

I can confirm there is no misprint in the equations.

@cirr
A+A+A=60
3A=60
A=20

A+B+B=30
20+2B=30
B=5

B-(C^2) = 3 (Two flowers without any symbols assumed to be ^2)
C=2^1/2

C+A*B= 2^1/2+20*5 = 101.414
by Order of Operations as no bracket is provided.

Am i right?

So our resident Einstein thinks there is only algebra involved in the test?

 

[Mista]

Should we count the petals for the yellow flowers that can be seen too instead of the number of yellow flowers?

The following is supposedly one of the maths problems in entrance exams for kindergarden kids to get into elementary school in Shanghai.

Brain-splitting equation that even a MATHS TEACHER can't solve has the entire Internet baffled... So do YOU know the answer?

• The controversial maths puzzle uses flowers instead of numbers
• People have been debating over the correct answer on Facebook
• The key is in the blue flowers having a different number of petals
• Even a maths teacher and puzzle 'professor' says it's unsolvable

It's the seemingly simple maths puzzle that is driving people on Facebook to despair as they debate what the correct answer is.

The puzzle, which was posted to Facebook page Trending in China, features flowers being used in place of numbers in equations.

It has drawn a lot of attention on the social media site, where it has had more than 1,200 likes and 1,700 comments.

Can you solve this? A maths puzzle that replaces numbers with flowers has created controversy on Facebook

In the puzzle, which is posted as a graphic, there are three lines showing what different combinations of flowers add up to. Then a new combination is shown, with no total, and it's up to people to work out the answer.

The first line shows three red flowers, which we are told add up to a total of 60. The second shows one red flower and two blue flowers, with a total of 30.

The third line shows one blue flower minus two yellow flowers, which equals a total of three.

The final line shows one yellow flower plus one red flower, multiplied by one blue flower. There is a question mark to indicate the answer not yet revealed.

Come on - Not very tough as you mentioned. The answer is 105.

Here is how......
20 + 20 + 20 = 60
20 + 5 + 5 = 30
5 – 2 = 3
1 + 20 x 5 = 105

Sorry, I'm not here for a silly back and forth trolling or an internet battle. Find somebody else for that.

I think the answer is still 101 based on colour of flowers. We are speculating about other answers just because we have been told that most straightforward answer is wrong.

This four petal flower is probably just a drawing oversight which no one noticed as number of petals were not important to begin with.


@cirr what do you think about it?

No. It was intent to trick people into thinkin the 4 petal flower is 5. It also trick to think 4 petal flower is 4. The size of 4 petal flower is also different. So we are dealing with infinite fraction 4 petal flower. That's why only infinite
∞ symbol should be put in that box as the best answer.
