B.

You are trying to find if F/J > 1?
(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) (10/100)*J = (4/100)*Total = (4/100)*(J+F)
=> F/J > 3/2
SUFFICIENT

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

Please explain part in bold...?

Is not

total=F+J-both(F&J)...?

though ultimate result does not change.

(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.


Given: J\geq{100} and 0.04*F=Both

Question: is F>J?

(1) Both=16=0.04*F --> F=400. We don't know J. Not sufficient

(2) 0.1*J=Both=0.04*F (given) --> 0.1*J=0.04*F --> \frac{F}{J}=\frac{10}{4} --> F>J. Sufficient.

Answer: B.
