Answer
Correct Answer: 46%
Explanation
### Concept & Percentage Relationship
To find what percentage one value ($X$) is of another value ($Y$), we use the formula:
$$ \text{Percentage} = \left( \frac{X}{Y} \right) \times 100 $$
Here, $X$ is the female athletes from Country E in 2009, and $Y$ is the total athletes (Male + Female) from Country B in 2008.
### Step-by-Step Solution
* Find the number of female athletes from Country E in 2009:
Value $X = 9.2$
* Find the total number of athletes from Country B in 2008:
Males = $11.4$, Females = $8.4$
Total $Y = 11.4 + 8.4 = 19.8$
* Apply the percentage formula:
$$ \text{Required \%} = \left( \frac{9.2}{19.8} \right) \times 100 $$
* Simplify the fraction to remove decimal points:
$$ \frac{92}{198} \times 100 $$
* Calculate the approximate value:
Since $198$ is very close to $200$, you can approximate the denominator to $200$.
$$ \frac{92}{200} \times 100 = \frac{92}{2} = 46\% $$
* The exact calculation is $46.46\%$, which safely rounds to the option $46\%$.
### Exam Strategy & Shortcut
Whenever your denominator is extremely close to a round number (like $198$ to $200$), round it to save time during the exam. $\frac{92}{200}$ is straightforward mental math ($92 \div 2 = 46$). Since the denominator was slightly increased for approximation, the actual value is slightly higher than $46$, making $46\%$ the perfect closest answer.
### Common Pitfall
A frequent error in "what percentage of..." questions is calculating relative to the wrong base or forgetting to sum the total participants (using only males or females for Country B instead of total). Always read carefully whether it asks for "male", "female", or "total" athletes.
### Final Answer
Therefore, the correct answer is **46%**.
