from the first summary bar graph number of people that had seen 0 to 5 movies = 25

from the second summary bar graph number of people that had seen 0 to 6 movies = 30

hence the number of people that had seen only 6 movies = 5

Again from the first summary graph number of people that had seen 6 to 10 movies = 30

we know that those who had seen 6 movies only = 5 people so

number of people who have seen 7 to 10 movies = 30-5 = 25

From the second summary graph we know that 7 to 12 movies = 35

since we have those who have seen 7 to 10 movies =25

number of people who have seen 11 or 12 movies = 35-25 = 10

(A)
