Q. 23

# Mark the correct

Let U be the set of students which are interviewed by investigator

A be the set of students which take milk

B be the set of students which take coffee

C be the set of students which take tea

Then ,n(U)=100 ,n(A)=12, n(B)=5 ,n(C)=8

Also, (ABC) means students who drink all of three=10

(AB) means students who drink milk and coffee =20-10=10

(BC) means students who drink coffee and tea =20-10=10

(AC) means students who drink milk and tea =25-10=15

ABC is the total of above =12+5+8+10+10+15+10=70

The number of students who didn’t take any drink =100-70=30
