Question
Out of 6000 participants in a conference in 2021, 70% were
women and the rest were men. In 2022, the number of women increased by 30% while the number of men decreased by 10%. Calculate the percentage change in the total participants in 2022 as compared to 2021.Solution
ATQ,
Number of women in 2021 = 6000 × 0.70 = 4200
Number of men in 2021 = 6000 - 4200 = 1800
Number of women in 2022 = 4200 × (13/10) = 5460
Number of men in 2022 = 1800 × 0.90 = 1620
Total participants in 2022 = 5460 + 1620 = 7080
So, percentage change in total participants = {(7080 - 6000) / 6000} × 100 = 18%
