Answer: 20 students do not take either coffee or tea
Step-by-step explanation:
Number of students in school hostel = 100
Number of tea drinking students = 60
Number of coffee drinking students = 50
Number of coffee and tea drinking students = 30
So, 30 students drink only tea and 20 drink only coffee.
30+30+20=80
100-80=20
So, 20 students take neither tea, nor coffee.
