    170 students liked reading mystery stories.

    Step-by-step explanation:

    In order to find this, we first must find the total number of students. We can do this by dividing the number who did not like reading mystery stories (30 student) by the percentage of the overall that it represents (15%)

    30/.15 = 200 students

    Now that we know how many students there are, we can multiply that by the percentage who like mystery stories to get the number.

    200 students *.85 = 170 students
