Let's solve this step-by-step math riddle using the given equations. We'll assign variables to each fruit:

- Let Apple = A
- Let Banana = B
- Let Coconut = C

Now, let’s write down the equations based on the image:

---

Equation 1:

🍎 + 🍎 + 🍎 = 30
So:
3A = 30
→ A = 10

✔ So, Apple = 10

---

Equation 2:

🍎 + 🍌 + 🍌 = 18
We know A = 10, so:
10 + B + B = 18
10 + 2B = 18
2B = 8
→ B = 4

✔ So, Banana = 4

Wait! But look at the banana in the third equation — it has only one banana, not two.

Let’s check the images carefully.

In Equation 2:
There are two bunches of bananas, and each bunch has two bananas → so total of 4 bananas?

But wait — actually, in the image, each banana icon appears to be a bunch of two bananas. So:

- One banana icon = 2 bananas → value = 4 (from earlier calculation)
But we need to verify if the banana symbol represents one banana or a bunch.

Let’s re-analyze.

---

Actually, from the second equation:

🍎 + 🍌 + 🍌 = 18
We already have Apple = 10
So:
10 + B + B = 18 → 2B = 8 → B = 4

So each banana icon (which is a bunch of two bananas) = 4
Therefore, each single banana = 2

But we’ll keep B as the value of one banana icon (i.e., a bunch of 2 bananas), so B = 4

---

Equation 3:

🍌 - 🥥 = 2
We have B = 4
So:
4 - C = 2
→ C = 2

✔ So, Coconut = 2

But wait — look at the coconut: it shows half a coconut in the subtraction. In the last equation, it’s a whole coconut.

Important detail!

In Equation 3:
🍌 - 🥥 = 2
The coconut shown is half a coconut (split into two halves). So this means:

If half a coconut = C/2, then:

B - (C/2) = 2
We already have B = 4
So:
4 - (C/2) = 2
→ C/2 = 2
→ C = 4

So a whole coconut = 4
And half coconut = 2

✔ So now we know:
- Apple = 10
- Banana (bunch of 2) = 4
- Half coconut = 2 → Whole coconut = 4

---

Final Equation:

🥥 + 🍎 + 🍌 = ??

Now, what do we have?
- Coconut: whole coconut → value = 4
- Apple: 10
- Banana: bunch of 2 bananas → value = 4

So:
4 + 10 + 4 = 18

✔ Final answer: 18

---

✔ Answer: 18

---

Summary:

- Apple = 10
- Banana (bunch of 2) = 4
- Half coconut = 2 → Full coconut = 4
- Last line: 4 (coconut) + 10 (apple) + 4 (banana) = 18

✔️ Answer: 18
