People watching Television is 65%. People watching only Television is 65% - 25% = 40%
People reading newspaper is 40%. People reading only newspaper is 40% - 25% = 15%
Thus percentage of people watching TV, reading newspaper and
Both TV and newspaper is 40% + 15% + 25% = 80%
Hence percentage of people neither watching TV nor reading newspaper is 100% - 80% = 20%
