Neither statement alone gives enough information but using both statements together, you get

Total = n(G) + n(F) - Both + None

160 = 90 + 85 - Both + None

Both - None = 15

Number of students studying both is 15 more than the number of students studying neither. Sufficient.

the number of students studying German and French = n(G) + n(F) - Both
number of students studying neither German nor French = None

Question is asking 'the number of students studying ( Not written BOTH) German and French is how much greater than the number of students studying neither German nor French?'

So, Basically
[n(G) + n(F) - Both] - None =???

in that case the Ans should be E

what i am missing ?

{n(G) + n(F) - Both} is the number of students studying German OR French (including Both). It is not the number of students studying German and French.
No. of students studying German AND French = Both

So the question asks us the difference between Both and None.

T=160

1) G=90 NS alone

2) F=85 NS alone

1&2) T=G+F-Both+Neither
Neither->160-90=70
Both->160-70=90+85-Both->Both=85
Both-Neither->85-70=15
