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