Select the correct answer. This table shows information on types of fragrances sold to men and women in a day at a beauty supply

maria [59]

Answer: C. 27% of men like woody fragrances, and 45% of the people who like citrus fragrances are women

Step-by-step explanation:

Here, Given table,

Citrus Fruity Woody

Men : 27 21 18

Women : 22 26 15

Thus, The percentage of men like woody fragrances

= $\frac{\text{Number of men who like woody fragrance}}{\text{total number of Men}} \times 100$

= $\frac{18}{66}\times 100$

= $\frac{1800}{66}$

= 27.2727..... %

≈ 27 %

Now, The percentage of men like woody fragrances

= $\frac{\text{Number of women who like citrus fragrance}}{\text{total number of persons who like citrus}} \times 100$

= $\frac{22}{49}\times 100$

= $\frac{2200}{49}$

= 44.8979591837 %

≈ 45 %

Thus, Option C is correct.
