Study the given diagram carefully and answer the question. The numbers in different sections indicate the number of persons. How many Africans are there who are also authors?
This question tests your ability to interpret data from a Venn diagram. The diagram shows the overlapping categories of Africans, Authors, and Doctors.
To find the number of Africans who are also authors, we need to look at the section where the "African" circle and the "Author" circle overlap. This section represents the number of individuals who are both African and Authors.
Step-by-Step Solution:
- Locate the overlapping area of the "African" and "Author" circles in the Venn diagram.
- Identify the number written within that overlapping area. The number is 22.
- Therefore, there are 22 Africans who are also authors.
Why other options are incorrect:
- Option 1 (14): This number represents only a part of the Africans who are authors; it doesn't include all the individuals in the overlapping area.
- Option 3 (8): This is the number of people who are only Africans and not Authors or Doctors.
- Option 4 (45): This number is too high and does not reflect any section in the Venn diagram; it's likely a sum of several sections.
Final Answer: The correct answer is 22.
