85 book in total 20% of 85 is 17.00 17 mysteries + 18 adventures = 35. 
85 - 35 is 50 fantisies

Total number of books =85

20% of books are mystery books = 20% of 85 = 0.2*85 = 17

So number of mystery books =17

Number of adventure stories =18

Number of fantasy books = total number of books - (number of mystery books + number of adventure stories)

Number of fantasy books = 85 -(17+18) = 85 - 35 = 50

Answer : Number of fantasies in the library are 50.
