Here's the answer ?:

Let's break down the puzzle step-by-step to find the values of each fruit.

1. First equation (3 apples):

   $$\text{apple}+\text{apple}+\text{apple}=30$$

   This implies that each apple is worth 10.

   $$\text{apple}=10$$

2. Second equation (1 apple and 2 bunches of bananas):

   $$10+\text{bananas}+\text{bananas}=18$$

   Subtracting 10 from both sides:

   $$2\times \text{bananas}=8$$

   So, each bunch of bananas is worth 4.

   $$\text{bananas}=4$$

3. Third equation (1 bunch of bananas and 2 coconut halves):

   $$4-\text{coconuts}=2$$

   Subtracting 4 from both sides:

   $$\text{coconuts}=2$$

   This means that each coconut half is worth 1 (since there are two halves in the picture).

4. Final equation: The last line shows one coconut half, one apple, and one bunch of bananas:

   $$\text{coconut half}+\text{apple}+\text{bananas}=??$$

   Substituting the values we found:

   $$1+10+4=15$$

The answer is 15.
