In a town, 40% of the male population and 45% of the female population are married. Find the ratio between male and female population in the town assuming that one man marries one woman and vice versa.
A
8 : 9
B
9 : 8
C
5 : 7
D
7 : 5
Correct Option:
B
Explanation
Let the male population be M and the female population be F. Since each married man corresponds to one married woman, 40% of M = 45% of F. Thus 0.40M = 0.45F, so M/F = 45/40 = 9/8. Therefore, the male:female ratio is 9:8.
