| **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.
