The country’s population is 241.7 million people. The number of persons aged 30-39 is 15.6%, there are 967 men per 1000 women. Determine the number of women at this age.
1) Let’s determine the number of persons aged 30-39 years, making the proportion:
241.7 million people = 100%
X = 15.6%,
X = 37705200 people
2) Let’s make an equation with 2 unknowns:
1000X + 967X = 37705200
1967 X = 37705200,
X = 19168
3) Substitute in the equation and find the number of women:
1000 x 19168 = 19 million 168 thousand people.
Answer: The number of women aged 30-39 is 19 million 168 thousand people.
