Children's Addition And Subtraction Maths Task Is Baffling Adults Online (But It's Really Quite Simple)

A children's maths task which uses pieces of fruit to add and subtract seems to be baffling parents and adults online.

Mum Thighler Perry tweeted a picture of the brainteaser saying it was "driving Facebook crazy".

The task is to work out the missing value on the fourth sum, by finding the values of an apple, banana and coconut.

But if you break it down, it's really not that hard.

Perry's post of the brainteaser was retweeted more than 700 times.

The many people replying had very different answers. Here's an example of the confusion.

Where does the problem lie? People not paying attention to how many pieces of fruit there are in the questions.

If you look closely, the bunch of bananas in the last line has one less banana than the previous two lines.

The coconut in the final line is half the amount of the previous line.

And that's it. That's where the confusion is coming from.

Here's how we worked it out.

It starts off quite simple, with three apples giving the total value of 30. People seem to agree that one apple therefore equals 10.

The next sum is quite easily solved, too. One apple (10) plus two bunches of bananas equals 18. So each bunch of four bananas comes to the value of four, and one banana is worth one.

The next sum shows than a bunch of bananas minus a coconut equals two. So the coconut must be worth two.

Half a coconut plus an apple, plus three bananas therefore should equal 14.

Do you agree? Let us know in the comments below.
