At least 100 students at a certain high school study Japanese. If 4 percent of the students at the school who study French also study Japanese, do more students at the school study French than Japanese?

1) 16 students at the school study both French and Japanese

2) 10 percent of the students at the school who study Japanese also study French

I got B
used a little different approach for 2nd statement

You are trying to find if F/J > 1?

1 st- copied from bbk post

(1) 16 students study both Japanese and French, that's 4% of the total number of students given from the question. So you have

16 = (4/100) * Total

Total = 400 students

You know that at least 100 students study Japanese and 16 studied both. So it could be that 101 students studied Japanese 299 studied French, or vice versa. INSUFFICIENT

(2) since # of students studying both is the same, I mean it is one.

we have 0.04(French)=0.1(Japanese)----->ratio of French to Japanese is more than 1

Sufficient
