IMO B

This is a weighted average problem and as per statement 2 we can definetely say that atleast 10 % of the people are 65 years or over as it gives the percentage of men and women who are 65 or over

Statement 1 says 11.3% 0f the population is 65 yrs old or older than that but it fails to provide any data about number of working people in this age. Hence insufficient

Statement 2 says among the people who are 65 years old or older 20% of the men and 10% of the women are working.

In general weightage problem if you say of the population comprising x and y kind of people 10% of x and 20% of y are working total % of population working will definitely be between 10 and 20% Hence statement 2 alone is suffiecient.

Hence B

Let me know if you have any queries.
