Question

In the diagram below, the circle stands for 'educated', square stands for 'hard working', triangle for 'urban people' and rectangle for 'honest'. The different regions of the diagram are numbered from 1 to 12. Study the diagram carefully and answer the question.

Uneducated urban hard-working and honest people are indicated by:

• A. 3
• B. 11
• C. 9
• D. 4

Hint:

Find the region inside the triangle, square and rectangle that still falls outside the educated circle.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
In this diagram, four shapes stand for four qualities: the circle means "educated", the square means "hard working", the triangle means "urban people", and the rectangle means "honest". We are asked to find the region number that stands for people who are urban, hard working and honest, but NOT educated.

Step 2: Key Formula or Approach:
We need a region that is inside the triangle (urban), inside the square (hard working) and inside the rectangle (honest), but lies outside the circle (so not educated).

Step 3: Detailed Explanation:
Region 4 is exactly this patch, it lies inside the triangle, inside the square and inside the rectangle, but the circle's boundary does not extend into it.
So a person placed in region 4 is urban, hard working, and honest, but not educated. Checking the other options, region 3 is only inside the triangle and square but not inside the rectangle, so it misses "honest". Region 11 is inside the square and rectangle only, so it misses "urban". Region 9 is inside the square, circle and rectangle but not inside the triangle, and it wrongly includes "educated".

Step 4: Final Answer:
Region 4 is the only region that is urban, hard working and honest while staying outside the educated circle.
