A sample study of the people of an area revealed that total number of ...
Given Information:
- Total number of women = 40%
- Percentage of coffee drinkers = 45%
- Percentage of male coffee drinkers = 20%
To Find: Percentage of female not-coffee drinkers
Solution:
Let's assume that the total number of people in the area is 100.
- Total number of women = 40% of 100 = 40
- Total number of men = 100 - 40 = 60
We know that the percentage of coffee drinkers is 45%.
- Total number of coffee drinkers = 45% of 100 = 45
We also know that the percentage of male coffee drinkers is 20%.
- Total number of male coffee drinkers = 20% of 100 = 20
Using the above information, we can calculate the total number of female coffee drinkers.
- Total number of female coffee drinkers = Total number of coffee drinkers - Total number of male coffee drinkers
- Total number of female coffee drinkers = 45 - 20 = 25
Now, we can calculate the total number of female not-coffee drinkers.
- Total number of female not-coffee drinkers = Total number of women - Total number of female coffee drinkers
- Total number of female not-coffee drinkers = 40 - 25 = 15
Finally, we need to find the percentage of female not-coffee drinkers.
- Percentage of female not-coffee drinkers = (Total number of female not-coffee drinkers / Total number of people) x 100%
- Percentage of female not-coffee drinkers = (15 / 100) x 100%
- Percentage of female not-coffee drinkers = 15%
Therefore, the correct answer is option (B) 15.
