Question

the total number of the student 50 in a class out of 45 student passed in mathematics then find percentage student passed in mathematics​

Answer 1

Answer:

Let M= The set of students passed in Mathematics

     S= The set of students passed in Science

Then, n(S)=28,n(M∩S)=10,n(M∪S)=50

We have n(M∪S)=n(M)+n(S)−n(M∩S)

50=n(M)+28−10

⇒n(M)=32

Aliter

From the Venn diagram

x+10+18=50

x=50−28=22

Number of students passed in Mathematics =x+10=22+10=32
