1道簡單數(shù)學題卻有4種答案？連老外都懵圈了

Are you a mastermind mathematician ? Try your hand at this puzzle—and you won't even need a calculator to solve it. This problem may be billed as an “easy” brainteaser for children, but it has left even the most advanced puzzle solvers scratching their heads.

你是一位擅長謀劃的數(shù)學家嗎?試試這道謎題，你甚至不需要計算器就可以解決它。對孩子們來說，這個難題也許“很簡單”，但它還是讓最優(yōu)秀的解謎者們感到困惑。

If you ask most Internet users, you'll find that there is a huge range of possible answers. People have argued that the final number could be anything from 14 to 15 to 16 to 20.

如果你問一下多數(shù)網(wǎng)友，你就會發(fā)現(xiàn)有許多可能的答案。大家爭論道，最終的答案可能是14,15,16或20中的任何一個。

 

At first glance, those who answered 16 appear to have it right. Let's do the math, as explained by the problem:

乍看之下，回答16的那些人似乎是正確的。根據(jù)這個問題給出的信息，我們一起算一下：

3 apples = 30, so 1 apple = 10.

3個蘋果=30，所以1個蘋果=10

10 + 2 bananas = 18, so 2 bananas = 8 and 1 banana = 4.

10+2捆香蕉=18，所以2捆香蕉=8，1捆香蕉=4

4 – 1 coconut = 2, so 1 coconut = 2.

4-1個椰子=2，所以1個椰子=2

Therefore, 1 coconut + 1 apple + 1 banana = 2 + 10 + 4 = 16

因此，1個椰子+1個蘋果+1捆香蕉=2+10+4=16

It’s not quite that easy, though. If you take a closer look at the photos, you’ll notice that each bunch of bananas contains four bananas. However, the one in the final equation only has three bananas. Same goes for the coconut; while the third equation has one coconut, the last one has only one-half of a coconut.

然而，這個問題并沒有那么簡單。如果你仔細看看圖片，你就會注意到，每捆香蕉有4根。然而，最后一個等式里的香蕉只有3根。椰子也是一樣的，第三個等式里有一個椰子，但最后一個等式里只有半個椰子。

Keeping those details in mind, let’s try again.

考慮到這些細節(jié)，我們再試一次。

3 apples = 30, so 1 apple = 10.

三個蘋果=30，所以1個蘋果=10

10 + 8 bananas = 18, so 8 bananas = 8 and 1 banana = 1.

10+8根香蕉=18，所以8根香蕉=8,1根香蕉=1

4 – 1 coconut = 2, so 1 coconut = 2.

4-1個椰子=2，所以1個椰子=2

Therefore, 1/2 coconut + 1 apple + 3 bananas = 1 + 10 + 3 = 14.

因此，1/2個椰子+1個蘋果+3根香蕉=1+10+3=14

So, the correct answer is 14. Right?

所以，正確答案是14。對嗎?

Well, actually, due to the puzzle’s vague instructions, “there are an infinite amount of possible answers,” Dr. Kevin Bowman said.

好吧，實際上，因為這個謎題的說明很含糊，所以“有許多可能的答案”，凱文·鮑曼博士說道。
