no. of members who have both hats and shoes=
18 - 9 = 9

no. of members who have hats = 45 - 18 = 27

no. of members who have hats only hats = 27 - 9 = 18.

no of students have both shoes and hats is: 9 since 18 have shoe not mention about hat so (18-9)
no of students have shoe alone is:9
 from the total students 45, 45-(9+9)=27

since their are 9 members with shoes only and 9 others with hats and shoes so if we have to select one of the options we have to go with 27

As the question says find those who have only hats the answer is 27....
total students with shoes=18(among these 9 dont have hats)
so no. of students with only hats=45-18=27

27

B-cause.

There is three groups.

1. Shoes and NO Hat

2. Shoes and Hat

3. No Shoes and Hat

<<If there is some members who doesn't hav anything,

the question hav to mention about that. BUT! There is no mention about that.

so, I can suppose that there is no member who doesn't hav anything. >>

group 1 = 9

group 2 = 18 - 9 = 9

SO, Group 3 = 45 -9 -9 = 27

there is the 27 members who doesn't hav shoes .

use the venn diagrams formulae : A union B = A + B - A intersection B
where AUB=45 (total)
           no.of people who've shoes A=18
           no.of people who've hats B=?
           no.of people who've only shoes but not hats A-B = 9
           no.of people who've shoes and hats A n B = 9
           no.of people who've only hats but not shoes B-A = ?
apply formula
   45=18+B-9
=> B=36
=> B-A= 36-9
           =27
  Ans:c

Let n(A-B) eqaqls 9 {shoes but not hat}

n(A) eqals 18 {shoes}

then we have find n(b-a)?

given n(AorB) eqals 45

clearly member have both shes and hat eqals 9

using venn diagram

45 eqals 9+9+n(B)

Answer - 27
