Solution:

total students: 243 + 567: 810

Students who wore costumes: 243

Students who did not wear costumes: 567

Now, the percentage of students who wear a costume is given by the following diagram:

By cross-multiplication, we get:


x\text{ (810)=(100)(243)}

solving for x, we get:


x\text{ = }((100)(243))/(810)=30

so that, the correct answer is:

30 percent.
