Mastering Syllogism for IBPS PO: Venn Diagram Method
Syllogism tests your ability to derive logical conclusions from given statements. IBPS PO presents 2-3 statements followed by 2-4 conclusion options, asking which conclusions logically follow.
Statements: "All managers are leaders. Some leaders are entrepreneurs."
Conclusions: (I) Some managers are entrepreneurs. (II) All leaders are managers.
The Venn diagram method gives 100% accuracy if applied correctly. Draw overlapping circles representing each category mentioned in statements. This visual representation eliminates confusion and prevents logical errors.
Step-by-Step Syllogism Solving Technique
Rule 1: Universal Statements Create Subsets
"All A are B" means A is completely inside B. Draw a small circle (A) inside a larger circle (B). Every element of A is automatically B, but not every B is A.
Rule 2: Particular Statements Create Intersections
"Some A are B" means circles A and B overlap partially. The overlapping region contains elements that are both A and B. Never assume all A are B or all B are A from "some" statements.
Rule 3: Negative Statements Show Separation
"No A are B" means circles A and B don't touch at all. They're completely separate. This is the easiest case—just draw two separate circles.
Priya from Lucknow improved her syllogism accuracy from 60% to 95% in 3 weeks by practicing 10 Venn diagrams daily. She now solves syllogism questions in under 35 seconds during mocks.
Common Syllogism Question Types in IBPS PO
Type 1: Two Universal Statements
Statements: "All doctors are professionals. All professionals are educated."
Conclusion: "All doctors are educated" → Always True
When both statements use "All," you can create a direct chain. A⊂B and B⊂C means A⊂C automatically.
Type 2: One Universal + One Particular
Statements: "All engineers are graduates. Some graduates are scientists."
Conclusion: "Some engineers are scientists" → May or May Not Be True
You cannot conclude anything definite when "some" appears in the second statement.
Type 3: Complementary Pairs
If two conclusions are complementary ("Some A are B" and "Some A are not B"), at least one must be true.
IBPS PO tests this concept in 30% of syllogism questions.
Blood Relations: The Generation Chart Method
Blood relations test your ability to decode family relationships from complex descriptions. IBPS PO typically gives 3-5 sentences describing relationships, then asks specific questions about family connections.
Draw a vertical generation chart with three levels: grandparents at top, parents in middle, children at bottom. Use symbols consistently: Male = ○, Female = △, Marriage = =
Decoding Complex Blood Relation Statements
Critical Symbols to Master
- Brother's wife = Sister-in-law (Bhabhi)
- Sister's husband = Brother-in-law (Jija)
- Father's/Mother's brother = Uncle (Chacha/Mama)
- Father's/Mother's sister = Aunt (Bua/Mausi)
Common IBPS PO Patterns
Pattern 1: Introducing Someone's Relative
"Pointing to a photograph, Rajesh said: 'His mother is the wife of my father's son.'"
Solution: "My father's son" = Rajesh himself (or his brother). "Wife of my father's son" = Rajesh's wife. So the person in the photo is Rajesh's son.
Pattern 2: Multiple Generation Links
"A is B's sister. C is B's mother. D is C's father. E is D's mother."
Solution: Create the chart: E (great-grandmother) → D (grandfather) → C (mother) → A and B (siblings). Relationship between A and E? A is E's great-granddaughter.
Blood Relation Shortcuts for IBPS PO
Shortcut 1: Gender Identification
If the question asks about "uncle," "father," "brother," the answer is always male. Eliminate female options immediately.
Shortcut 2: Generation Counting
Count the number of relationship words. "Father's father" = 2 generations up = Grandfather. "Sister's daughter's son" = 2 generations down = Grand-nephew.
Amit from Chennai solved 4/4 blood relation questions in IBPS PO 2024 Prelims by drawing family trees in 20 seconds before reading questions. This preparation time saved him from re-reading statements multiple times.
Coding-Decoding: Pattern Recognition Strategies
Coding-decoding questions test pattern identification skills. IBPS PO presents words or numbers in coded format, asks you to decode new words, or identify the coding pattern.
Three Main Types in IBPS PO
Type 1: Letter Shifting (Most Common - 40% of Questions)
Example: If MANGO is coded as OCPIQ, how is APPLE coded?
Solution: Each letter shifts +2 positions. M→O, A→C, N→P, G→I, O→Q
Apply same to APPLE: A→C, P→R, P→R, L→N, E→G = CRRNG
Quick Pattern Recognition: Check if the first letter's shift matches the second letter's shift. If MANGO shows M→O (+2) and A→C (+2), the pattern is consistent forward shifting.
Type 2: Word-to-Number Coding
Example: In a certain code, TEACHER is written as 7512859, STUDENT is written as 3746127. What is the code for TUTOR?
Solution: Identify letter-to-number mapping: T=7, E=5, A=1, C=2, H=8, R=9, S=3, U=4, D=6
TUTOR = T-U-T-O-R = 7-4-7-?-9
Notice O isn't in the original words. This question is unsolvable or requires assumption. In exams, eliminate such options if they appear.
Type 3: Conditional Coding (Advanced - IBPS PO Mains)
Example: In a certain code language:
- "sky is blue" is coded as "ta me jo"
- "blue and red" is coded as "me po ka"
- "red is bright" is coded as "po ta si"
Solution: Find common words and codes: "blue" appears in sentence 1 and 2, common code is "me"; "is" appears in sentence 1 and 3, common code is "ta"; Therefore in sentence 1: "sky" = "jo"
Neha from Pune mastered this technique by practicing 5 coding-decoding sets daily for 2 weeks. Her solving time dropped from 60 seconds to 30 seconds per question.
