Ok - lets make a grid
---------------Japanese-----------non-Japanese------------Total
French------------16 ----------------------- ----------------------F
non-French-------J-16 ----------------------- ----------------------X-F
Total--------------J-----------------------X-J----------------------X
Let the total number of children who speak french and japanese = X
Total number of students who speak Japanese = J
J>100
Total number of students who speak french = F
or F = X-J
4% of students who speak F = 4F/100
Statement 1:
students who speak both French and Japanese = 16
No info on students who don't speak Japanese or who don't speak French.
Need that info to complete the grid.
statement I - INSUFFICIENT
Statement II
10% of students who speak Japanese also speak french.
Therefore, 10J/100 = 4F/100
10J = 4F
5J = 2F
F/J=5/2
Or - More students speak french than Japanese
Statement II is sufficient.
imo B
