Question

In a survey of students, each student selected from a list of 12 songs the 2 songs that the student liked best. If each song was selected 4 times, how many students were surveyed?

Answer 1

Explanation:

If every song was picked once the students would be 12/2=6 since every single one of them picked two.

Now the songs are selected four times. So it is quadruple the amount of students from before thus 4*6=24
