that i guess
Given:
Total number of students = 100
Number of students who drink tea= 76
Number of students who drink coffee = 54
Number of students who drink both coffee tea = 45
To find:
Number of students who drink neither coffee nor tea
Solution:
We can solve this question using Venn Diagram (attached below).
Number of students who only drink tea (yellow) = Number of students who drink tea - Number of students who drink both coffee tea
= 76 - 45 = 31 students
Similarly, students who drink only coffee (pink) = 54 -45 = 9 students
Number of students who drink neither coffee nor tea = Total number of students - Number of students who drink tea - Number of students who drink both coffee tea - Number of students who drink only coffee
= 100 - 31 - 45 - 9
= 100 - 85
= 15 students.
Hence, 15 students drink neither tea nor coffee.
