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.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.

设学French的人一共有F，学Japanese的一共有J，两种语言都学的有B人，已知B=0.04F。
Statement1：B=16=0.04F，则F=400，但是J>=100，两者无法比较出大小。
Statement2: B=0.1J=0.04F，可得F/J=10/4=5/2，即F>J
