Given : In an examination, 80% students passed in Science, 70% in Mathematics and 60% in both science and Mathematics.
65 students failed in both subjects
To Find : what is the total number of students?
Solution:
Total Students = 100 %
Passed in Science = S = 80%
Passed in Mathematics = M = 70 %
Passed in Both = S ∩ M = 60 %
Failed in Both = F %
=> Total = S + M - S∩M + F
=> 100 = 80 + 70 - 60 + F
=> F = 10
10 % Failed in both
65 students failed in both subjects
10% = 65
100 % = 650
Total Students = 650
