Options

A. `9:8`
B. `7:9`
C. `7:3`
D. `5:6`

Answer

To solve the problem of finding the ratio of total sales in the two years of Company C2 and the ratio of total sales in both years of Company C4, we can follow these steps:

### Step 1: Identify Sales Data
First, we need to gather the sales data for Company C2 and Company C4 for the years 2020 and 2021.

Assuming the sales data from the graph or table is as follows:
- **C2 Sales:**
- 2020: 75 (in thousands)
- 2021: 85 (in thousands)

- **C4 Sales:**
- 2020: 95 (in thousands)
- 2021: 105 (in thousands)

### Step 2: Calculate Total Sales for Company C2
Next, we calculate the total sales for Company C2 over the two years:
\[ \text{Total Sales of C2} = \text{Sales in 2020} + \text{Sales in 2021} = 75 + 85 = 160 \text{ (in thousands)} \]

### Step 3: Calculate Total Sales for Company C4
Now, we calculate the total sales for Company C4 over the two years:
\[ \text{Total Sales of C4} = \text{Sales in 2020} + \text{Sales in 2021} = 95 + 105 = 200 \text{ (in thousands)} \]

### Step 4: Find the Ratio of Total Sales
Now, we can find the ratio of total sales between Company C2 and Company C4:
\[ \text{Ratio of Total Sales (C2 : C4)} = \frac{\text{Total Sales of C2}}{\text{Total Sales of C4}} = \frac{160}{200} \]

### Step 5: Simplify the Ratio
To simplify the ratio, we divide both the numerator and the denominator by their greatest common divisor (GCD), which is 40:
\[ \frac{160 \div 40}{200 \div 40} = \frac{4}{5} \]

### Final Answer
The ratio of total sales in the two years of Company C2 to the total sales in both years of Company C4 is:
\[ \text{Ratio (C2 : C4)} = 4 : 5 \]
