Answer :
There were 13 students on the wrestling team.
First, we need to calculate how many students are involved in student sports:
20% of 520 students = 0.20 x 520 = 104 students
Then, we need to calculate how many of those students were on the wrestling team:
12.5% of 104 students = 0.125 x 104 = 13 students
Therefore, there were 13 students on the wrestling team.
