Solution
After plotting the 3-circle Venn diagram, we get :
People who read only A: 59
People who read only B: 41
People who read only C: 41
People who read only A&B: 26
People who read only B&C: 14
People who read only A&C: 11
People who read all 3: 9
People who read none of the 3: 27
Hence,
Number of people who read two or less number of newspapers = 211
