in a survey of 60 people,it was found that 25 people read newspaper H, 26 read newspaper T, 26 read newspaper I, 9 read both H & I, 11 read both H & T, 8 read both T & I, 3 read all three newspaper. find the number of people who read exactly one news paper

 n(h)=25,n(i)=26,n(t)=26

h^i=9;h^t=11;i^t=8;i^h^t=3

n(hUtUi)=60

=>60=X-9-11-8+3

X=35

This question can be solved using venn diagram.
The answer will be:
The people who read only newspaper H =  8

n(h)=25, n(t)= 26 ,n(i)=26 , n( H ∩ I) = 9, n(H ∩ T)=11 , n(T ∩ I)=8 , N(H ∩ T ∩ I)=3 , 

N(H∪T)= n(h)+n(t)+n(i)+ n( H ∩ I)+ n(H ∩ T) + n(T ∩ I) +N(H ∩ T ∩ I)
 

N(H∪T=25+ 26+26+9+11+8+3
N(H∪T=108

n( H n T n I )+ n(H n T n I) + n(H n T n I)
Here H= 8, T= 10 & I = 12
No. Of newspaper who reads exactly one newspaper = H + I + T
= 8 + 12 + 10
= 30 sns
