From the given pie charts, find X (the percentage of people who like Reading). The percentage of people who like movies is 4% less than that of the people who like playing.
28
Percentage of people who like playing = % of football + % of cricket = 25 + 13 = 38 %.
So, percentage of people who like movies = 38% - 4% = 34%. So, percentage of people who like Reading = 100% - (34% + 38%) = 100% - 72% = 28%.
So, X = 28.
