Question 2042
Since there are 12 people in total, that means there’s 4 women and 8 men. There needs to be 20% women, so because we know that 4 is 20% of 20, that means that there has to be a total of 20 people. If you add 8 men to the already existing 12 workers, you’ll have 20. You’ll end up with 4 women which is 20% of 20, and 16 men which is 80% of 20. 
The answer is add 8 men.
