70 students are majoring in both, psychology & business

If 73% of the students are psychology majors, we know that
27% are not psychology majors. By the same reasoning, 38%
are not business majors, because 62% of the students do
major in business. So: 27 + 38 = 65

65% of the students are not majoring in both psychology &
business, so 35% are double majors, a total of 70 students.
