Explanation:

No. of people who read Hindu = 285

No. of people who read TOI = 127

No. of people who read IE = 212

Now,

No. of people who read Hindu and TOI both is = 20

No. of people who read TOI and IE both is = 35

No. of people who read Hindu and IE both is = 29

Let No. of people who read Hindu , TOI and IE all is = x ;

So, only Hindu is = 285-20-29-x = 236-x ;

Only TOI is = 127-20-35-x = 72-x ;

Only IE is = 212-35-29-x = 148-x ;

Now, 236-x + 72-x + 148-x + 20 + 29 + 35 + x + 50 = 500 590 -2x = 500

So, x = 45 this is the value who read all the 3 dailies.

So, No. of people who read only one paper is = 236-45 + 72-45 + 148-45 = 191 + 27 + 103 = 321.
