In a factory, the ratio between the number of men and women is 3:2. On one day, 18 men and 7 women were absent due to bad weather, and the ratio between the number of men and women present became 9:7. What is the actual number of women in the factory?
- 46
- 34
- 78
- 42
Correct answer: 42
Solution
Let men and women be \(3x\) and \(2x\). After absences, they become \(3x-18\) and \(2x-7\), and their ratio is 9:7. Solving gives \(x=21\), so the number of women is \(2x=42\).
