This is what you should be able to get from the information in the question.

You’ve put six for like all fruit but it says five in the text. I always found it helpful to work backwards on Venn diagrams when I did them. Once you start filling it in it become easier.

Solution is here:

Do the highlighted bits first:
10 - 5 = 5
17 - 5 = 12

The you can work out the other missing areas by adding (12 + 4 + 5 = 21) and subtracting from 40 gives 19.
(19 + 5 + 5 = 29) 30 - 29 = 1
and
(12 + 5 + 5 = 22) 30 - 22 = 8

Summing everything inside the circles: 4 + 19 + 1 + 12 + 5 + 5 + 8 = 54
None =. 100 - 54 = 46

Hope this is helpful.

I hope im not bothering but I wanna ask, in the question they stated at least one likes all of them, so that was my issue because when i added all of it, it doesnt give 100? So do we ignore that and we put the rest in none category like you did?

The question does not say that at least one person likes all the fruits, it says that everyone likes at least one fruit (meaning that there are no people who dislike all the fruits).

So have I goofed with my solution?

I don't think that the question can be correct, otherwise the numbers don't add up in the circles. There should be some there who don't like fruit as only 54 people are inside the circles meaning 46 should be outside.

It would probably be best if you started again. Start in the middle and work outwards. The question tells you that five people like all three fruits. Not six, five. Start there.

Ah yes, I can see now that I was replying to the wrong post/person. I thing there is a contradiction in the question. If 40 liked apples, 30 liked bananas and 30 liked grapes, and if everyone liked at least one fruit, then there could be no overlaps between the bubbles in the Venn diagram, as 40 + 30 + 30 = 100. However the question goes on to describe the various overlaps.
