1. The number of students studying German is 90.
2. The number of students studying French is 85.

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.
