In the following figure, the square represents dieticians, the triangle represents botanists, the circle represents psychologists and the rectangle represents Indians. Which set of letters represents the psychologists who are also botanists?
To solve the problem, we need to identify which set of letters represents psychologists who are also botanists. Let's analyze the given Venn diagram:
The diagram uses different shapes to represent different professions and attributes:
- Circle - Psychologists
- Triangle - Botanists
- Square - Dieticians (not needed to solve this particular question)
- Rectangle - Indians (not needed to solve this particular question)
We are looking for the intersection of the circle (psychologists) and the triangle (botanists). This intersection will give us the set of letters representing people who are both psychologists and botanists.
From the diagram:
- The triangle, representing botanists, contains the letters: A, B, E.
- The circle, representing psychologists, contains the letters: A, B, C, D.
The intersection of the triangle and circle includes the letters: A and B.
Therefore, the correct set of letters representing psychologists who are also botanists is AB.
Conclusion: The correct answer is AB.
