Then how many people read only one newspaper?1. 123 2. 213 3. 312 4. 321

Answer»

4. 321

Let number of people who read Hindu, TOI and IE all is = x 

So, only Hindu is = 285 – 20 – 29 – x = 236 – x 

So, only TOI is = 127 – 20 – 35 – x = 72 – x 

So, 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 newspapers. 

So, number of people who read only one paper is

 = 236 – 45 + 72 – 45 + 148 – 45 = 191 + 27 + 103 = 321
