We have to determine whether at least 10 percent of the people in Country X who are 65 years old or older employed.

Let's take each statement one by one.

1) In Country X, 11.3% of the population is 65 years old or older.

We have no information about the percent of the people in Country X who are 65 years old or older employed. Insufficient.

2) In Country X, of the population 65 years old or older, 20 percent of the men and 10 percent of the women are employed.

The weighted average of the number of men employed and the number of women employed would be greater than 10% (between 10% and 20%). Thus, we can conclude that at least 10 percent of the people in Country X who are 65 years old or older employed.

The correct answer: B

Hope this helps!
