Charlotte needs to arrange 20 chairs.

She has platforms that hold 4, 10 or 12 chairs.

Which of the following show how she could arrange exactly 20 chairs?

Select **all** the correct answers.

3 platforms of 12

5 platforms of 4

2 platforms of 10

2 platforms of 4

Let's analyze each option to see if the total number of chairs adds up to exactly **20** chairs.

### Step-by-Step Testing:

1. **3 platforms of 12**:
   \[
   3 \times 12 = 36
   \]
   This is **more than** 20 chairs, so this is not correct.

2. **5 platforms of 4**:
   \[
   5 \times 4 = 20
   \]
   This equals exactly 20 chairs, so this is **correct**.

3. **2 platforms of 10**:
   \[
   2 \times 10 = 20
   \]
   This equals exactly 20 chairs, so this is **correct**.

4. **2 platforms of 4**:
   \[
   2 \times 4 = 8
   \]
   This is **less than** 20 chairs, so this is not correct.

### Conclusion:
The correct answers are:
- **5 platforms of 4**
- **2 platforms of 10**
