I see 4 bananas on all pictures. Or atleast 4 banana bottoms.
So I will say answer is 15.

If the symbol for banana (value 4) and coconut (value 2) simply mean banana and coconut, the answer would be 16.

But if the numbers of bananas and coconuts in the images really count, then the answer is 14 (1 + 10 +3). So dude in #6 is right.

I thought about it , I went bananas , then I went nuts (coco), so my final answer is - pineapple.
