110 Number of men who liked fencing
=
15 x 2 u
= 0.4 u
Number of women who liked fencing
= 2 u - 0.4 u
= 1.6 u
Number of men who disliked fencing
=
110 x 1 u
= 0.1 u
Number of women who disliked fencing
= 1 u - 0.1 u
= 0.9 u
Total number of men
= 0.4 u + 0.1 u
= 0.5 u
Total number of women
= 1.6 u + 0.9 u
= 2.5 u
Women : Men
0.5 : 2.5
(x2)1 : 5
Answer(s): 1 : 5
