Question :
In a school hostel, there are 100 Students out of which,
60 drink tea, so doint coffee and 30 drink both tea.
and coffee. Find the numbers of student who do not
take tea or coffee?
Actually there is a mistake in the question
Expalnation:
Total no. of students = 100
No. of students who drinks coffee= 50
No. of students who drinks tea=60
No. of students who drinks both tea and coffee= 30
No. of stidents who drinks tea or coffee=(60+50) - 30 [ minus 30 because students who drinks both tea and coffee are already included in the list who drink tea and cofee separately]
= 110-30 = 80
No. of students who do not take tea or coffee = 100-80
= 20
Answer :
20
Hope my answer helps you
Answer:
Ans-- 10
Step-by-step explanation:
Total student in school = 100 student
No.of students drink tea = 60
No.of students drink coffee = 30
So,
60+30 = 90 students
Students Who do not take tea or coffee are
Total student - Total students of drink tea and coffee
100 - 90
= 10 students
Thus , 10 students who do not take tea or coffee.
