Find the number of people who like Candy Crush but do not like Chess.
Explanation:
Number of people who like Candy Crush = 500 – 280 = 220 Number of people who like Chess = 500 – 260 = 240 Number of people who like Temple Run = 500 – 310 = 190
20 people like all the three games
100 people like both Candy Crush and Chess ∴ Number of people liking only Candy Crush and Chess = 100 – 20 = 80
90 people like both Chess and Temple Run ∴ Number of people liking only Chess and Temple Run = 90 – 20 = 70
60 people like both Candy Crush and Temple Run ∴ Number of people liking only Candy Crush and Temple Run = 60 – 20 = 40
We can make the following Venn Diagram:
∴ Number of people who like Candy Crush but do not like Chess = 220 – 80 – 20 = 120
Hence, 120.
