Question

In an examination, 70% of students passed in physics, 65% in chemistry, 27% failed in both subjects. The
percentage of students who passed is:
(a) 66%
(b) 62%
(c) 69%
(d) None of these

Answer 1

62 percentage takes in exam

Answer 2

Answer:

the percentage of students who passed in both the subject is b) 62%

Step-by-step explanation:

Given that 70% of students passed in physics

=> % of students failed in physics = 30 %

65% of students passed in chemistry

=> % of students failed in chemistry = 35 %

students failed in both the subject = 27 %

students failed in at least one subject = 30 + 35 - 27 = 38%

=> students passed in both the subject = 100 - 38 = 62 %

Hence the percentage of students who passed in both the subject is 62 %
