C. The number of men in a community is 2,400. If the ratio of women to men in the community is 5:4, find
i. The total number of people in the community.
ii. The number of women in the community.
iii. How many more women are there than men if 400 men joined the community.

I. 5,400
ii. 3,000
iii. 200

Total number of parts the population is divided into: 5+4=9.

We know that 2,400 relates to the 4 parts of the ratio, so one part is 2,400 : 4 = 600.

i) So, in total, there are 600 (measure for one part) * 9 (total number of parts) = 5400 people in the community

ii) There are 5 parts in the women’s community. So, total number of women: 5 * 600 = 3000

iii) There we’re originally 5400 - 3000 = 2400 men in the community. If 400 more join, there will be 2400+400 = 2800 men.

So, there are still 3000 women and now 2800 men, so the difference between these is 3000-2800= 200.

There are 200 more women than men if 400 men joined the community.

Hope that’s helpful :)

The answer is all about the number 4
