With proper understanding of Venn diagram formulas and regular practice of Venn diagram questions with answers, you can solve these questions quickly in SSC, Banking, and other competitive exams.

    What is Venn Diagram in Reasoning? Definition and Basic Concept

    A Venn diagram is a graphical representation of sets using circles, where each circle represents a group and overlapping regions show common elements.

    Understanding Venn Diagram with Easy Explanation

    In Venn diagram reasoning questions, different categories (like students, players, or subjects) are shown using circles. The overlapping parts indicate common elements, while non-overlapping parts represent unique elements.

    Key Features of Venn Diagram Questions

    • Uses circles to represent sets

    • Shows relationships like common and distinct elements

    • Widely used in logical reasoning and set theory questions

    • Common in SSC Venn diagram questions and banking exams

    Importance of Venn Diagram Questions for SSC, Banking & Competitive Exams

    Venn diagram is a scoring topic in reasoning sections of competitive exams.

    Why Venn Diagram Questions are Important for Exams

    • Frequently asked in SSC CGL, CHSL, IBPS, SBI, and RRB exams

    • Helps test logical thinking and analytical ability

    • Easy to solve with proper Venn diagram tricks and formulas

    Why Venn Diagram is a High-Scoring Topic

    Basic Concepts of Venn Diagram and Set Theory in Reasoning

    Understanding basic set theory Venn diagram concepts is essential for solving all types of Venn diagram reasoning questions.

    Understanding Sets, Subsets, and Universal Set in Venn Diagram

    Set in Venn Diagram Reasoning

    A set is a collection of objects, numbers, or elements. Each circle in a Venn diagram represents a set.

    Subset Concept in Venn Diagram

    A subset is a part of a larger set. In diagrams, one circle may lie completely inside another, representing subset relationships.

    Universal Set in Venn Diagram Questions

    The universal set includes all elements under consideration and is usually represented by a rectangle enclosing all circles in Venn diagram questions.

    Union, Intersection, and Complement in Venn Diagram (Key Formulas & Concepts)

    Union of Sets (A ∪ B)

    Represents all elements belonging to either set A or set B or both. It includes the entire area of both circles.

    Intersection of Sets (A ∩ B)

    Represents common elements between sets A and B. It is shown by the overlapping region in Venn diagram reasoning questions.

    Complement of a Set (A')

    Represents elements that are not in set A but are part of the universal set. It is the area outside the circle.

    These concepts are widely used in Venn diagram formula-based questions.

    Types of Venn Diagram Reasoning Questions (SSC, Banking & Competitive Exams Guide)

    Understanding the different types of Venn diagram reasoning questions is essential to solve problems quickly and accurately. In exams, Venn diagram questions with answers are asked in various formats, testing your ability to interpret relationships, classify data, and apply Venn diagram formulas and tricks effectively.

    Venn Diagram for a Relation (Set-Based Representation Questions)

    These are the most common Venn diagram reasoning questions, where you are given a relationship and asked to represent it using a diagram.

    What are Relation-Based Venn Diagram Questions?

    In these questions, statements like “All A are B” or “Some B are C” are given, and you need to choose the correct diagram that represents the relationship.

    How to Solve Relation-Based Venn Diagram Questions

    • Identify keywords like all, some, none

    • Translate statements into set relationships

    • Match with the correct Venn diagram representation

    These questions are frequently asked in SSC Venn diagram reasoning questions.

    Relation to Venn Diagram Questions (Reverse Logic Type)

    These questions are the opposite of the above type.

    What are Reverse Venn Diagram Questions?

    A diagram is given, and you need to identify which statement or relationship it represents.

    How to Solve Reverse Venn Diagram Questions

    • Observe overlapping and non-overlapping regions

    • Identify relationships between sets

    • Match with the correct statement

    This type tests your understanding of set theory Venn diagram concepts.

    Caselet-Based Venn Diagram Questions (Data Interpretation Type)

    These are slightly advanced Venn diagram reasoning questions.

    What are Caselet Venn Diagram Questions?

    A paragraph or data set is given with information about different groups, and you need to represent or analyze it using a Venn diagram.

    How to Solve Caselet-Based Questions

    • Extract key data from the passage

    • Convert information into sets

    • Apply Venn diagram formulas to find answers

    These are common in banking and higher-level reasoning exams.

    Representation-Based Venn Diagram Questions (Logical Classification)

    These questions focus on classification and grouping.

    What are Representation-Based Venn Diagram Questions?

    You are given categories like “Fruits, Apples, Mangoes” or “Students, Boys, Girls,” and asked to choose the correct diagram representing their relationship.

    How to Solve Representation-Based Questions

    • Identify subset or overlapping relationships

    • Check if categories are independent or related

    • Choose the correct Venn diagram representation

    These are widely asked in logical reasoning Venn diagram questions.

    Let’s discuss these types in detail with the help of examples -

    1. Venn Diagram to Relation

    In this type of Venn diagram, a Venn diagram will be given, and we have to determine the most suitable group of words that matches the relationship with the given Venn diagram. Let’s understand the concept with the help of Venn diagram examples with solutions.

    Example: Select the set of classes and the relationship among them that is best illustrated by the Venn diagram given below.

    Venn Diagram

    A) Shoes, Watches, Goggles

    B) Spectacles, Pens, Diaries

    C) Reptiles, Snakes, Lizards

    D) Daughter, Son, Brother

    Answer: To identify the words associated with the given Venn diagram, let's analyse the diagram. The diagram consists of two small circles within a larger circle, indicating that the two circles belong to the same category represented by the larger circle. Since the two small circles do not intersect or overlap, they do not share any similarities. Now, if we check the options, it is clear that only the third option satisfies the condition stated by the given Venn diagram. In this case, both snakes and lizards fall under the category of reptiles and are not interconnected.

    2. Relation to Venn Diagram

    In this type of Venn diagram, a group of words will be given and we have to find the most suitable Venn diagram that represents the possible relationship between the given words. Let’s understand the concept with the help of Venn diagram examples with solutions.

    Example: Determine the Venn diagram that represents the relationship between Omnivores, Bear, and Deer.

    Answer: As we know, Deer only eats grass. This means that deer is a herbivore and not an omnivore. But, a Bear is both a carnivore and herbivore, i.e., a Bear is an omnivore. So, all bears are omnivores while no deer is omnivore. Deer and bears are not related to each other. So, the circle representing the bear will lie inside the circle representing the omnivore, and the circle representing the deer will be drawn separately.

    So, the Venn diagram is –

    Venn Diagram

    3. Caselets

    Data Caselet questions are mostly seen in the reasoning section of the CAT exam. This topic is very important from the CAT exam and bank exams point of view. In these types of questions, candidates are given a caselet and a set of questions are asked based on the given caselet. A data caselet is basically a paragraph that contains certain data or information. No charts or graphs are provided with the data. We have to organise the data from the caselet and then solve the related set of questions. Some questions can be solved by using the table and some questions can be solved directly just by interpreting the data. Some of the questions are solved using the Venn diagrams. The questions are easily solvable as only basic mathematical concepts are used to answer most of the questions.

    Example: In a batch of 60 students, 50% of the students scored more than 80% and 70% scored more than 50% in a test. There were 10% of the students who scored less than 15 on that test. How many students scored between 15 and 60 marks if the total marks were 75?

    Solution: Total marks = 75

    80% of 75 = (80/100) × 75 = 60

    Students who scored more than 60 = 50% of 60 = 30 —---- (I)

    Students who scored less than or equal to 60 = 30 —---- (II)

    Students who scored less than 15 = 10% of 60 = 6 —---- (III)

    Now, on subtracting equation (III) from equation (II), we will get the students who score between 15 and 60.

    So, students who scored between 15 and 60 = 30 - 6 = 24

    4. Representation-Based Venn Diagram

    In this type of Venn diagram, a Venn diagram will be given with different geometrical shapes indicating different categories with one or more than one numbers in each figure. In this, we have to identify how many persons belong to different categories according to the given conditions. Let’s understand the concept with the help of Venn diagram examples with solutions.

    Example: In the given figure, how many people like cricket and tennis?

    Venn Diagram

    Answer: To get the number of people who like cricket and tennis, determine the sum of the numbers falling in the part of the diagram where the regions representing Cricket, Hockey and Tennis overlap. In the below diagram, the shaded part represents the region common to both cricket and tennis as well as hockey. The numbers of the asked fields that fall in the hockey region will also be counted as there is no direction given that the region belonging to hockey can not be included.

    Venn Diagram

    The total number of people who like cricket and tennis both = 17 + 15 = 32

    Therefore, 32 people like both cricket and tennis. Hence, the second option is correct.

    Therefore, the Venn diagram is as follows –

    Venn Diagram

    Hence, the first option is correct.

    Venn Diagram Reasoning Practice Questions For Caselets

    Q1. Directions: At a certain school, each of the 150 students takes at least 1 of the three 3 classes. The 3 classes available are English, Hindi, and Spanish. 60 students study English, 85 study Hindi, and 52 study Spanish. If 5 students take all 3 classes, then how many take exactly 2 classes?

    A) 22

    B) 25

    C) 31

    D) 37 (Correct)

    Solution: Based on the above-given data, let’s consider the following Venn diagram:

    Venn Diagram

    According to the diagram,

    a + b + c + x + y + z + 5 = 150

    a + b + c + x + y + z = 145 —------(I)

    Also, a + b + c + 2(x + y + z) + 3(5) = 60 + 85 + 52

    a + b + c + 2(x + y + z) + 15 = 197

    a + b + c + 2(x + y + z) = 182 —------(II)

    To get the number of students who take exactly 2 classes, subtract equation (I) from the (II).

    (x + y + z) = 182 - 145 = 37

    So, 37 students took exactly 2 subjects. Hence, the fourth option is correct.

    Q2. In a locality, there are a total of 500 families. Each family reads at least 1 newspaper. It is known that 250 families read ‘The Hindu’, 180 families read ‘Times of India’, and 200 families read ‘Indian Express’. If it is known that exactly 50 families read all three newspapers then how many families read exactly 2 newspapers?

    A) 22

    B) 30 (Correct)

    C) 35

    D) 27

    Solution: Based on the above-given data, let’s consider the following Venn diagram:

    Venn Diagram

    According to the diagram,

    a + b + c + x + y + z + 50 = 500

    a + b + c + x + y + z = 450 —------(I)

    Also, a + b + c + 2(x + y + z) + 3(50) = 250 + 180 + 200

    a + b + c + 2(x + y + z) + 150 = 630

    a + b + c + 2(x + y + z) = 480 —------(II)

    To get the number of students who take exactly 2 classes, subtract equation (I) from the (II).

    (x + y + z) = 480 - 450 = 30

    So, 30 families read exactly 2 newspapers. Hence, the second option is correct.

    Q3. Directions: There are 450 students in a college. Each student has to choose one or more electives out of economics, geography, and math. Further, the following information is also known:

    1. 80 students selected only economics and math.

    2. 91 students selected only economics and geography.

    3. 60 students selected only math and geography.

    4. The number of students who selected only geography is 145 less the number of students who selected only economics.

    5. In total 250 students selected economics as an elective.

    6. In total 255 students selected geography as an elective.

    How many students selected both math and economics as electives?

    A) 85

    B) 91

    C) 95

    D) 99 (Correct)

    Solution: Let ‘x’ be the number of students who took all the three electives and ‘y’ be the number of students who took only economics as an elective. Based on the given information, the Venn diagram is as follows:

    Venn Diagram

    Let’s consider the students who took economics as an elective, we have,

    91 + 80 + x + y = 250 ⇒ x + y = 79 —-------(I)

    Let’s consider the students who took geography as an elective, we have,

    91 + x + 60 + 145 - y = 255 ⇒ y - x = 41 —-------(II)

    Adding both the equations, we get, 2y = 120 ⇒ y = 60

    So, x = 19

    So, number of students who took all the three as electives = 19

    Number of students who took only economics as an elective = 60

    Number of students who took only geography as an elective = 85

    Number of students who took only math as an elective = 450 - 255 - 60 - 80 = 55

    Thus, we got the following Venn diagram:

    Venn Diagram Reasoning

    Number of students who selected both economics and math as electives = 80 + 19 = 99

    Hence, the fourth option is correct.

    Q4. Directions: There are 450 students in a college. Each student has to choose one or more electives out of economics, geography, and math. Further, the following information is also known:

    1. 80 students selected only economics and math.

    2. 91 students selected only economics and geography.

    3. 60 students selected only math and geography.

    4. The number of students who selected only geography is 145 less the number of students who selected only economics.

    5. In total 250 students selected economics as an elective.

    6. In total 255 students selected geography as an elective.

    How many students selected only economics as an elective?

    A) 80

    B) 60 (Correct)

    C) 55

    D) 19

    Solution: Let ‘x’ be the number of students who took all the three electives and ‘y’ be the number of students who took only economics as an elective. Based on the given information, the Venn diagram is as follows:

    Venn Diagram Reasoning

    Let’s consider the students who took economics as an elective, we have,

    91 + 80 + x + y = 250 ⇒ x + y = 79 —-------(I)

    Let’s consider the students who took geography as an elective, we have,

    91 + x + 60 + 145 - y = 255 ⇒ y - x = 41 —-------(II)

    Adding both the equations, we get, 2y = 120 ⇒ y = 60

    So, x = 19

    So, number of students who took all the three as electives = 19

    Number of students who took only economics as an elective = 60

    Number of students who took only geography as an elective = 85

    Number of students who took only math as an elective = 450 - 255 - 60 - 80 = 55

    Thus, we got the following Venn diagram:

    Venn Diagram

    Number of students who selected only economics as an elective = 60

    Hence, the second option is correct.

    Q5. Directions: 500 people are living in a particular village. There are three drinks Tea, Coffee, and Hot chocolate available in the village. Each citizen has to vote for one or more of the three drinks which he/she likes. It is known that:

    1. In total 180 people like Tea and 220 people like Coffee.

    2. 60 people like all the three drinks.

    3. 80 people like both Tea and Hot chocolate.

    4. 79 people like both Hot chocolate and Coffee.

    5. 91 people like both Tea and Coffee.

    How many people like only Tea?

    A) 69 (Correct)

    B) 59

    C) 60

    D) 70

    Solution: According to the given information, 46 people like all three drinks. For the given data, the Venn diagram is as follows:

    Venn Diagram

    Since, 80 people like both Tea and Hot chocolate. So, the number of people who like only Tea and Hot chocolate = 80 - 60 = 20

    Since, 79 people like both Hot chocolate and Coffee. So, the number of people who like only Hot chocolate and Coffee = 79 - 60 = 19

    Since, 91 people like both Tea and Coffee. So, the number of people who like only Tea and Coffee = 91 - 60 = 31

    Thus, we got the following Venn diagram:

It tests skills like comprehension, pattern recognition, and critical thinking, which are crucial for various competitive exams. Below are the important verbal reasoning topics you should focus on during your preparation.

    Venn Diagram Important Formulae

    This section brings together the most useful formulas you’ll need to handle set-based questions quickly and accurately. It gives you a crisp collection of results that make solving union, intersection, and complement problems far more intuitive during exams.

    ConceptFormulaDescription
    Union of Two Sets$n(A \cup B) = n(A) + n(B) - n(A \cap B)$Core formula for 2-set Venn diagrams
    Intersection of Two Sets$n(A \cap B) = n(A) + n(B) - n(A \cup B)$Derived from the union formula
    Only in A$n(\text{Only A}) = n(A) - n(A \cap B)$Removes overlap
    Only in B$n(\text{Only B}) = n(B) - n(A \cap B)$Similar treatment
    Neither A nor B$n(\text{Neither}) = n(U) - n(A \cup B)$Useful in probability & DI
    Union of Three Sets$n(A \cup B \cup C) = n(A) + n(B) + n(C) - n(A \cap B) - n(B \cap C) - n(A \cap C) + n(A \cap B \cap C)$Standard 3-set formula
    Exactly One of Three$n(\text{Exactly 1}) = [n(A) + n(B) + n(C)] - 2[n(A\cap B) + n(B\cap C) + n(A\cap C)] + 3n(A\cap B\cap C)$Good for puzzle questions
    Exactly Two of Three$n(\text{Exactly 2}) = n(A\cap B) + n(B\cap C) + n(A\cap C) - 3n(A\cap B\cap C)$Removes triple intersection
    None of Three$n(\text{None}) = n(U) - n(A \cup B \cup C)$For complements
    Complement$n(A') = n(U) - n(A)$Works for any set

    4)
    Venn Diagram

    Solution

    As we know, educated people are the ones who go to educational institutions to acquire academic qualifications. So, we can say that all graduates will be educated because without acquiring a degree, a person cannot be called a graduate. On the other hand, not all educated people or graduates need to be employed because some might go for higher studies, or might contribute towards social work. So, some graduates/educated may be employed, some may be unemployed. Therefore, the circle of graduates lies inside the circle of educated, and the circle of unemployed intersects the circle of graduates and educated.

    So, according to the above information, the Venn diagram will be as follows –

    • Draw the required circles representing each set clearly without overlapping unnecessarily.

    • Mark the given data (numbers or elements) in the appropriate regions of the diagram.

    • Fill from the intersection first (common elements), then move to the exclusive areas.

    • Cross-check that the total number of elements matches the data given in the question.

    Common Mistakes to Avoid in Venn Diagram Reasoning

    • Misplacing numbers in the wrong sections of the diagram.

    • Overlapping circles incorrectly, leading to logical inconsistency.

    • Ignoring zero or empty intersections when mentioned in the question.

    • Forgetting to verify that the sum of all regions equals the total given in the problem.

    Short Tricks and Tips for Venn Diagram Questions with Solutions

    • Always start from the smallest intersection and move outward.

    • Use symbols or abbreviations for quick marking in exam conditions.

    • If options are given, use back-solving to eliminate incorrect diagrams quickly.
