14 Number of men who liked gymnastics
=
310 x 2 u
= 0.6 u
Number of women who liked gymnastics
= 2 u - 0.6 u
= 1.4 u
Number of men who disliked gymnastics
=
14 x 1 u
= 0.25 u
Number of women who disliked gymnastics
= 1 u - 0.25 u
= 0.75 u
Total number of men
= 0.6 u + 0.25 u
= 0.85 u
Total number of women
= 1.4 u + 0.75 u
= 2.15 u
Women : Men
0.85 : 2.15
(x20)17 : 43
Answer(s): 17 : 43
