Answer:
52 students
Step-by-step explanation:
Let's assume A represents number of students in the library means A=86,
B represents number of student in student union means B = 78
U represents total students surveyed means U = 136
section II represents number of students in library and student union means
II = 34
Now from figure we can see
number of students only in library is represented by section I .
and section I can be written as
I = A - II
I = 86-34 = 52
only in Union represents III
III = B - II
III = 78-34 = 44
not in library or not in union = U - (I + II + III)
= 136 - (52+ 34+ 44)
= 136 - 130 = 6
