a. 11.3% of population is 65 or over
b. Of those 65 and older, 20% of men and 10% of women are employed
Answer: B

pls help
a) Insufficient - No data is provided how much of these 11.3% is employed or not
b) Sufficient - Whatever be the mix of men and women in 65+ population at least 10% will be employed (extreme case when all the 65+ are women)

Answer: B

pls help
Statement a:- No mention of employment .Hence,insufficient.
Statement b:- Overall we find that total % is greater than 10% since 20 % of men + 10% of women > 10% of men + 10% of women.

Hence,ans. should br B.

I hope you get the solving approach.:)
For any doubts post subsequently.HTH
It takes time and effort to explain, so if my comment helped you please press Thanks button :)



Just because something is hard doesn't mean you shouldn't try,it means you should just try harder.
