# Questions on Venn Diagram (Verbal Reasoning for SSC, CAT, Bank PO)

(01) Find suitable Venn Diagram for following relationships
Government Servants, Lecturers, Doctors

Sol: Let us consider two at a time

I) Government servants(G) and Lecturers(L)- Some G may be L or vice-versa

II) Lecturers (L) and Doctors(D)- some L may be D or vice versa

III) Some G may be D or vice-versa

As all three entities are related with each other. We can get our required venn-diagram by combining the above three diagram as below

Ans: Hence, option (4) is the correct answer.

(02) Which one of the following diagrams best depicts the relationship among Human Society – Youth Club, Political Party and Youths ?

Sol: Human society- Youth club (HSYC) as the name suggests might be an NGO or any other organisations by youths for Human society. It is a different body and is completely different from political party

Now, some Youths (Y) may be members of HSYC. So

Some Youths (Y) may be member of political party (PP). So

But HSYC is not related to PP in any means. So, without intersecting circle of HSYC and PP if we combine the above diagram. We will get our desired venn-diagram as below

Ans: Hence, option (2) is the correct answer.

(03) Find the Venn Diagram of following relationships
Children, Serious, Naughty

Sol: Serious and naughty are the nature or behaviour of the children.

Some children(C) may be serious(S). So

Some children may be naughty. So

But a naughty children cannot be serious at the same time or vice versa.
So we cannot intersect N and S in venn-diagram. So our desired venn- diagram will be as

Ans: Hence, option(1) is the correct answer

(04) Which figure best represents the relationship between Editor, Newspaper and Journalist?

Sol: Journalist– A journalist is a person who collects, writes, photographs, processes, edits or comments on news or other topical information to the public.

Editor– Newspaper editors assign, review, edit, rewrite, and lay out all copy in a newspaper except advertisements.

From above definition we are clear that Editor, Newspaper and Journalist all are different thing. But some how they are connected and related to each other.
So, we represent them in venn diagram as below.

Ans: Hence, option (4) is the correct answer.

(05) Which venn diagram represents the relation amongst rose, flower and leaves

Sol: Rose is a kind of flower and can be included under the class flower. So, we can represent both two as below

But leaves are different from flower. So, it should be shown separately in venn diagram as below

Ans: Hence, Option (1) is the correct answer.

(06) Identify the diagram that best represents the relationship among classes given below : Library, Books, Racks

Sol: Library is the place/room where we will found books. These books are stacked/kept in racks in library.
So, order of arrangement of these three entities should be

Libraryà Racksà Books And  venn-diagram can be drawn as below

Ans: Hence, option (2) is the correct answer

(07) Which of the following diagrams best represents cousins, nieces and females ?

Sol: Every Niece is necessarily a female according to her gender.
So, niece and female can be shown as

But cousins can be a male or female. Some cousins may be female or vice versa. So, circle for Cousins in venn-diagram should intersect circle for female

But some female cousins may be Niece too. So, our final venn-diagram will be drawn as below

Ans: Therefore, option(4) is the correct answer.

(08) Which one of the following figures best represents the relationship among Kitchen, House and Garden?

Sol: Kitchen is a part of house and is generally built inside House. No one builds kitchen outside his/her house.
So, kitchen and house can be shown in venn-diagram as below

But Garden is build outside house. So, garden can be shown in venn diagram as below

Ans: Hence, option (4) is the correct answer.

(09) Answer the question on the basis of the figures given below, that denote a set of classes. Pick out the figure that best denotes a particular group. Adults, Doctors, Pediatrician

Sol: Pediatrician– a doctor who deals with the diseases of children.
So, Pediatrician comes under the class Doctors.
Therefore, all Pediatrician are Doctors and all Doctors are adult, as to be a Doctor one must be an adult because a child can’t be a doctor. So, we can arrange the three entities as

And our required venn-diagram can be drawn as

Ans: Hence, option (3) is the correct answer

(10) Identify the diagram that best represents the relationship among classes given below: Universe, Stars, Sun

Sol: The Universe is all of space and time and their contents, including planetsstarsgalaxies, and all other forms of matter and energy.

A Star is an astronomical object consisting of a luminous spheroid of plasma held together by its own gravity. The nearest star to Earth is the Sun

In simple words Universe contains everything including stars and sun. And Sun is also a star. So order of arrangement of three entities is

Universe ⟹ Star⟹ Sun

We can draw venn-diagram as

Ans: Hence, option (2) is the correct answer.
