FS': (not spanish means s' and french means f)
A) 30% F insufficient
B) 40% s' -> 60% S insufficient
A&B) 100% = 30% + 60% - FS (both F and S) + none (some students don't study both)
Thus insufficient
IMO E

Let the total number of students = 100.
Statement 1: Total French = 30.
Statement 2: Since 40 students do NOT study Spanish, the total number of students who DO study Spanish = 60.
When the statements are combined, the following distribution is possible:
Number of students who study only French = 20.
The following distribution also is possible:
Number of students who study only French = 10.
Since the number of students who study only French can be different values, INSUFFICIENT.
The correct answer is E.

Thank you Guru ... but maybe i'm confused with the response. In the argument, the total number of students is 100, but in the venn diagram examples given the totals add up to a number less than 100 students ... A + B - Both + Neither, correct?
