### Answer:

##### 52

### Explanation:

Hey there, math quiz enthusiast! Ready for a brain teaser? Mathematics can be a whirlwind of numbers and equations, but fear not, we’re here to unravel the mystery together!

Let’s denote each of the images as A, B, and C as shown below:

The first equation states: A + A + A = 30. By combining like terms, we can simplify it to 3A = 30. Solving for A, we find that A is equal to 10.

Moving on to the second equation: A + B + B = 20. Since we know A is 10, we can substitute it into the equation. This gives us 10 + B + B = 20, which simplifies to 10 + 2B = 20. By subtracting 10 from both sides, we get 2B = 10. Solving for B, we find that B is equal to 5.

Now, let’s tackle the third equation: B + C + C = 9. Plugging in the value of B as 5, we have 5 + C + C = 9. Simplifying further, we get 5 + 2C = 9. Subtracting 5 from both sides, we find 2C = 4. Solving for C, we discover that C is equal to 2.

Now comes the grand finale! This is the part that confuses many! We need to use BODMAS/PEMDAS rule here. This rule stipulates that we carry out multiplication first before addition!

Therefore, let’s solve the expression C + B × A, where A = 10, B = 5, and C = 2.

First, we’ll perform the multiplication:

B × A = 5 × 10 = 50

Now, we can substitute the values back into the equation:

C + B × A = 2 + 50 = 52

Therefore, the result of the expression C + B × A, with A = 10, B = 5, and C = 2, is** 52.**
