A sample study of the people of an area revealed that total number of ...
Let's assume the total population is 100.
Out of which 40% are women.
ie; 40 women & 60 men.
Given that, 45 %of the total population drink coffee.
20% of the population who drink coffee are Male.
so the percentage of the female coffee drinker (45-20) = 25%.
If females = 40% and 25% drinks coffee.
Then females who don't drink Coffee = (40%-25%) = 15.

A sample study of the people of an area revealed that total number of ...
Given:
- Total number of women = 40%
- Percentage of coffee drinkers = 45%
- Percentage of male coffee drinkers = 20%

To find:
- Percentage of female non-coffee drinkers

Solution:
1. Let's assume that the total number of people in the area is 100.
2. From the given information, we can calculate the following:

- Total number of women = 40% of 100 = 40
- Total number of men = 100 - 40 = 60
- Total number of coffee drinkers = 45% of 100 = 45
- Total number of male coffee drinkers = 20% of 100 = 20

3. We can use the above information to find the total number of female coffee drinkers:

- Total number of female coffee drinkers = Total number of coffee drinkers - Total number of male coffee drinkers
= 45 - 20 = 25

4. Finally, we can find the percentage of female non-coffee drinkers:

- Total number of female non-coffee drinkers = Total number of women - Total number of female coffee drinkers
= 40 - 25 = 15

Therefore, the percentage of female non-coffee drinkers is 15%.

Answer: option B) 15
