A survey of 200 people in a community who watched at least one of the three channels — BBC, CNN and DD — showed that 80% of the people watched DD, 22% watched BBC, and 15% watched CNN.If 5% of people watched DD and CNN, 10% watched DD and BBC, then what percentage of people watched BBC and CNN only?

Applying AUBUC formula Let x be the number who watch BBC and CNN and y be the number who watch all three channels. 100 = 80+22+15-(10+5+x)+y x-y = 2 Hence only 2% people watch BBC and CNN only.
