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.

n(Urdu) = 73% = 146 Students

n(Persian) = 62% = 124 students

n(Total) = 200 students

so, 200 = 146 + 124 – x

x = 70 = 35% students major in both urdu and persian
