Find the total number of women who like only Red color. Correct Answer 12

Number of women who like Red color = 22

Number of women who like Blue color = 20

Number of women who like Yellow color = 19

Number of women who like both Red and Blue color = 5

Number of women who like both Yellow and Blue color = 5

Number of women who like both Red and Yellow color = 9

Number of women who like only Blue color = 14

Number of women who like all the three colors = 4

Number of women who like only Red color = 22 – 5 – 9 + 4 = 12

Hence, 12 is the correct answer.
