suppose total students - 100
20% not attending, remaining = 80

percentage required to get total students who accept = 100/80 = 1.25x

Hence D

20% of students who are accepted will not attend college.

(100-20)% of students who are accepted will attend the college
Let y = no of students that should be accepted to achieve a planned environment of x students.

80% of y = x
$$\frac{80}{100}\cdot y=x$$
$$\frac{0.8y}{0.8}=x$$
$$y-\frac{x}{0.8}=1.25x$$
$$Answer\ is\ Option\ D$$
