110 Number of men who liked badminton
=
310 x 2 u
= 0.6 u
Number of women who liked badminton
= 2 u - 0.6 u
= 1.4 u
Number of men who disliked badminton
=
110 x 1 u
= 0.1 u
Number of women who disliked badminton
= 1 u - 0.1 u
= 0.9 u
Total number of women
= 1.4 u + 0.9 u
= 2.3 u
Total number of men
= 0.6 u + 0.1 u
= 0.7 u
