110 Number of women who liked canoeing
=
310 x 4 u
= 1.2 u
Number of men who liked canoeing
= 4 u - 1.2 u
= 2.8 u
Number of women who disliked canoeing
=
110 x 1 u
= 0.1 u
Number of men who disliked canoeing
= 1 u - 0.1 u
= 0.9 u
Total number of men
= 2.8 u + 0.9 u
= 3.7 u
Total number of women
= 1.2 u + 0.1 u
= 1.3 u
