B. 0.5
C. 0.6233
D. 0.45

Answer

To find the percentage increase in the total cars in 2016 over 2012, we will follow these steps:

### Step 1: Identify the total number of cars in 2012 and 2016
From the information provided:
- Total cars in 2012 = 120,000
- Total cars in 2016 = 180,000

### Step 2: Calculate the increase in the number of cars from 2012 to 2016
To find the increase, we subtract the total number of cars in 2012 from the total number of cars in 2016:
\[ \text{Increase} = \text{Total cars in 2016} - \text{Total cars in 2012} \]
\[ \text{Increase} = 180,000 - 120,000 = 60,000 \]

### Step 3: Calculate the percentage increase
The formula for percentage increase is:
\[ \text{Percentage Increase} = \left(\frac{\text{Increase}}{\text{Original Number}}\right) \times 100 \]
Substituting the values we have:
\[ \text{Percentage Increase} = \left(\frac{60,000}{120,000}\right) \times 100 \]

### Step 4: Simplify the fraction
\[ \frac{60,000}{120,000} = \frac{60}{120} = \frac{1}{2} \]

### Step 5: Calculate the final percentage
Now, substituting back into the percentage formula:
\[ \text{Percentage Increase} = \left(\frac{1}{2}\right) \times 100 = 50\% \]

### Final Answer
The percentage increase in the total cars in 2016 over 2012 is **50%**.
