Question

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?

• A. 2%
• B. 5%
• C. 8.5%
• D. Cannot be determined

Answer 1

The correct option is A 2%

Since 80% watch DD, hence 20% do not watch DD. Let those who watch BBC and CNN only be x%, then 12 + 10 –x = 20

x = 2
