If I'm reading the problem correctly, you're trying to get x to be 100% (ie trying to fill the class completely). So if 20% of the accepted students don't go then you need accept 125% of applicants.

125*(1-20%)=125*.8=100

answer: 1.25x

But the question did not ask what percent should the college admit or if the college wants to admit all the students who apply. How did you make this deduction ?

I need a dicionary to translate English to English

100% is a given. You want to fill the class completely. If they didn't want this, they would specify that they only what X% of the seats filled.

If the class size is 100 (x), 20% of those accepted don't show up, then they need to accept 125 students. So 1.25*x is the answer.
