20100 =
15 Number of women who liked basketball
=
14 x 2 u
= 0.5 u
Number of men who liked basketball
= 2 u - 0.5 u
= 1.5 u
Number of women who disliked basketball
=
15 x 1 u
= 0.2 u
Number of men who disliked basketball
= 1 u - 0.2 u
= 0.8 u
Total number of men
= 1.5 u + 0.8 u
= 2.3 u
Total number of women
= 0.5 u + 0.2 u
= 0.7 u
Men : Women
2.3 : 0.7
