110 Number of women who liked aerobics
=
15 x 4 u
= 0.8 u
Number of men who liked aerobics
= 4 u - 0.8 u
= 3.2 u
Number of women who disliked aerobics
=
110 x 1 u
= 0.1 u
Number of men who disliked aerobics
= 1 u - 0.1 u
= 0.9 u
Total number of women
= 0.8 u + 0.1 u
= 0.9 u
Total number of men
= 3.2 u + 0.9 u
= 4.1 u
Men : Women
0.9 : 4.1
(x10)9 : 41
Answer(s): 9 : 41
