Question

In a college, of 200 students are randomly selected, 140 likes tea, 120 likes coffee and 80 likes both tea and coffee.

1. How many students like tea only?
2. How many students like neither tea nor coffee?
3.How many students like only coffee?

Answer 1

Explanation:

To find the number of students who like tea only, we need to subtract the number of students who like both tea and coffee from the total number of students who like tea.

So, students who like tea only = 140 - 80 = 60To find the number of students who like neither tea nor coffee, we need to subtract the total number of students who like either tea or coffee or both from the total number of students.

So, students who like neither tea nor coffee = 200 - (140 + 120 - 80) = 200 - 180 = 20To find the number of students who like only coffee, we need to subtract the number of students who like both tea and coffee from the total number of students who like coffee.

So, students who like only coffee = 120 - 80 = 40
