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.
