(1) In country x, 11.3 percent of the population is 65 years old or older.
(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.

PLEASE EXPLAIN....
(1) No info about employment: insufficient.

(2) if 20% of the old men are employed and 10% of the old women, then even if there's only 5 old men and 100 billion old women, more than 10% of the old people will be employed: sufficient.

(1) is insufficient and (2) is sufficient: choose (b).

Can anyone please explain me the question:-
Are at least 10 percent of the people in Country X who are 65 years old or older employed?

I'm bit confused here.

Thanks!

(1) In country x, 11.3 percent of the population is 65 years old or older.
(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.

PLEASE EXPLAIN....
No real math is needed here.

Statement 1: In country x, 11.3 percent of the population is 65 years old or older.
No information about who is employed.
Insufficient.

Statement 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.
10% of the women 65 or older are employed.
20% of the men 65 or older are employed.
Thus, when the women and men are COMBINED to form the ENTIRE population 65 or older, the percentage employed must be BETWEEN 10% and 20%.
Thus, at least 10% of the population 65 or older are employed.
Sufficient.

The correct answer is B.
