There is a tribal area in Australia called Xiamer and the existing tribal population is concentrated in that area. It is found that 45 percent of the men (above 18 years adult men) in that area are married to 25 percent of the women (who are above 18 and considered adult) in that area. What percentage of the total adult population is married?(One man marries one woman)
A 35
B 32.1
C 30.9
D 25
E Cannot be Determined
I believe the question means that there are no marriages outside the tribe.Let the number of men and women be m and n.
Since 45% of men are married to 25% of women, \(\frac{45m}{100}=\frac{25w}{100}........w=\frac{9m}{5}\)
Total strength = \(m+w=m+\frac{9m}{5}=\frac{14m}{5}\)
Total married people = Twice of men married, as for each man , there will be a woman married
\(=2*\frac{45m}{100}=\frac{9m}{10}\)
%\(=\frac{\frac{9m}{10}}{\frac{14m}{5}}*100=\frac{9*5}{10*14}*100=32.14\)
