Data Sufficiency

1) At least 100 students at a high school study Japanese. If 4% of the students who study French also study Japanese, Do more students at the school study French than Japanese?

A) 16 Students at the school study both French & Japanese.
B) 10% of those who study Japanese also study French.

Hi,

Statement 1:

16 students study F and J. There should be 400 students studying F. The number of J students could be any of 300 or 400 or 500 (lesser or greater? cannot tell).

Statement 2:

Let x be the number of students who study F and J.

x is 4% of F
x is 10% of J. This implies that J is definitely lesser than F.

Hence, sufficient.

Hope this helps. Thanks.
