Number of women who like Red colour = 22

Number of women who like Blue colour = 20

Number of women who like Yellow colour = 19

Number of women who like both Red and Blue colour = A + P = 5

Number of women who like both Yellow and Blue colour = C + P = 5

Number of women who like both Red and Yellow colour = B + P = 9

Number of women who like only Blue colour = Z = 14

Number of women who like all the three colours = P = 4

Number of women who like only Red colour = X

and X + A + B + P = 22

 X + 1 + 5 + 4 = 22

X = 12

Hence, 12 is the correct answer.
