No. Let me explain:Mr2Bits wrote:Is it just me or is the wording incorrect of this question?
If you have 400 students, 300 major in one subject and at least 20 major in each of the other 5 remaining subjects wouldn't that tap you out of students?
The logic seems off or maybe its just me.
If it's not, Answer D looks like a good guess to me.

300 students for majors 1st to 4th.
20 for the 5th major.
20 for the 6th major.
Therefore, we have 340 students allocated, with 60 remaining. If no one else graduates from 4th or 5th, then the other major takes the full 60, adding up to the minimum 20 students that we said. That adds up to 80.
