Answer 1

Answer:

I think 5 is the answer

Step-by-step explanation:

no of students =20

tea taken= 12

coffee=16

not anything=3

12+16-3=25

therefor 25-20=5

Answer 2

Answer:

11

Step-by-step explanation:

Total number of students = 20

Number of students take tea = 12

Number of students take coffee = 16

and the number of students take neither of them = 3

So, The number of students take either tea or coffee = 20 - 3 = 17

Also, The number of students take either tea or coffee = Number of students take tea + number of students take coffee - number of students take both

ie, 17 = 12 + 16 - number of students take both

So, number of students take both = 12 + 16 - 17 = 11
