Can GD do basic MathS? :p

You can work out the value of the apple though, the coconut and banana images on the bottom could represent any number at all without clarification,

Why are you able to work out the value of three apples but not three or four bananas?

It could be a picture of anything really, I'm only describing it as an an apple because that's what is. Picture A (apple) has a given value, Picture B (half a coconut) and Picture C (3 bananas) don't.

If a single apple has a value of 10 then you can't take the number of fruit literally.

I'm not following your argument here - there are three apples on the first line and you accept you're able to assign a value to them

But you've got an issue with there being three or four bananas, why?

If you know that 3 apples equal 30 and you're happy to accept that an individual apple is 10.

You know 4 bananas equal 4 but you're not happy to assign a value to three bananas???

You cannot say with any certainty at all that it is exactly 50% of a whole coconut, the break is jagged and uneven. ;)
 
Say it was written in algebra:

a + a + a = 30
a + b + b = 18
b - c = 2
y + a + z = ?

y and z are not given, therefore it's not possible to answer.

Even assuming that counting fruit is valid for all we know two of the four bananas could have been worth 1.5 and the other two 0.5 so taking one away results in 2.5 or 3.5, or like someone else said how do we know it's exactly half a coconut? and not two pieces valued at 0.4 or 0.6?

You can make an interpretation as to the answer but that's all imo, interpreting is not math.

/Sits on fence. :p

For all we know two of the four bananas could have been worth 1.5 and the other two 0.25 so taking one away results in 3 or 3.5, or like someone else said how do we know it's exactly half a coconut? and not two pieces valued at 0.4 or 0.6?

the coconut is a bit pedantic - it is clearly meant to be half a coconut

the bananas on the other hand - there were four of them now there are three - are you just having trouble with the fact they're bunched together rather than laid out in a row like the apples?

you can write it as

3a = 30
a + 8b = 18
4b - c = 2
0.5c + a + 3b = ?

you know what a banana is - assigning a different variable because there are three of them instead of four makes no sense

13.. then I saw the extra banana.:o Should have gone to Specsavers.:(

It's interesting re bananas in bunches that, without pause, people may either count 1 collection of 4 items as 1, or the elements of the collection as 4. But of course there's also the dilemma of a set of four sets, one element in each, adding up to five sets.:D But since the fruit are variables, replacing pictures with symbols dispenses with your visual sense getting in the way, which obviously is the 'trick' of the question.

3X = 30
X = 10

10 + 2Y = 18
2Y = 8
Y = 4


Y - Z = 2

4 - 2 = Z

Z = 2



X + 0.75(Y) + 0.5(Z) = V

10 + 3 + 1 = 14
Im sure this type of thing explains why my A turned into an E (I didnt spot the picture differences till posting :o).
Always write down workings in an exam
 
Is it the bananas that are supposed to trick people?

You could think of it as a bunch of bananas instead of 4 individual bananas in which case it is easy to overlook the 3 bananas bunch at the end.
 
Isn't it 12.75
4 bananas = 3, so three bananas = 2.25
Apple = 10
2 coconut halves = 1, so one coconut half = 0.5

Edit - Nope, it seems I can't do basic maths as I seem to think that 10 + 3 + 3 = 18. I'll hang my head in shame.
