The women's department of a store stocks have more types of white socks.
Step-by-step explanation:
Given:
The women's department of a store stocks 4 types of black socks for every 5 types of white socks.
Ratio of black socks to white socks = 4 : 5
The men's department stocks 6 types of black socks for every 7 types of white socks.
Ratio of black socks to white socks = 6 : 7
Each department has the same number of black socks.
Question asked:
Which department stocks more types of white socks?
Solution:
Let each department has 100 black socks.
<u>For women's department</u>
4 : 5 : : 100 : white socks

<u>For men's department</u>
6 : 7 : : 100 : white socks

We found that out of 100 black socks the women's department of a store stocks have 125 white socks while the men's department stocks have about 117 white socks then by default understood that the women's department of a store stocks have more types of white socks.
