70 students are majoring in both, Urdu & Persian
If 73% of the students are Urdu majors, we know that 27% are not Urdu majors. By the same reasoning, 38% are not Persian majors, because 62% of the students do major in Persian.
So: 27 + 38 = 65
65% of the students are not majoring in both Urdu & Persian, so 35% are double majors, a total of 70 students.
