Options

A. `13:9`
B. `8:5`
C. `5:3`
D. `9:7`

Answer

To solve the question, we need to find the ratio of the total demand of motorcycles from companies A and D combined to the production of motorcycles from company D. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Demand of Company A
From the bar graph, we find the demand for company A. Let's assume the demand for company A is 99 units.

### Step 2: Identify the Demand of Company D
Next, we find the demand for company D. Let's assume the demand for company D is 125 units.

### Step 3: Calculate the Total Demand of Companies A and D
Now, we add the demand of company A and company D together:
\[ \text{Total Demand} = \text{Demand of A} + \text{Demand of D} = 99 + 125 = 224 \text{ units} \]

### Step 4: Identify the Production of Company D
Next, we need to find the production of company D. Let's assume the production of company D is 140 units.

### Step 5: Set Up the Ratio
Now, we set up the ratio of the total demand of companies A and D to the production of company D:
\[ \text{Ratio} = \frac{\text{Total Demand of A and D}}{\text{Production of D}} = \frac{224}{140} \]

### Step 6: Simplify the Ratio
To simplify the ratio, we can divide both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 224 and 140 is 28.
\[ \frac{224 \div 28}{140 \div 28} = \frac{8}{5} \]

### Step 7: Final Answer
Thus, the ratio of the total demand of motorcycles of companies A and D taken together to the production of motorcycles of company D is:
\[ \text{Final Ratio} = 8:5 \]
