Puzzle Reasoning

Competitive exams often feature intricate reasoning puzzles that test logical deduction and systematic problem-solving. This session deepens understanding of these challenges, specifically addressing year-based puzzles and designation-based puzzles. Mastering these puzzle types, which involve chronological ordering, age calculations, and hierarchical arrangements, is crucial for improving analytical skills and securing higher scores in examinations like RBI Assistant.

Year-Based Puzzle (Problem 1)

This problem focuses on arranging seven individuals based on their birth years, calculating their ages relative to a base year (2021), and applying specific conditions to determine their final arrangement.

Solving Steps:

1. Arrange Years: Begin by listing the given birth years in chronological order.

• 1985, 1989, 1992, 1994, 1997, 2002, 2007

2. Calculate Ages: Determine each person's age by subtracting their birth year from the base year (2021). For instance, a person born in 1985 would be 2021 - 1985 = 36 years old.

• Ages: 36, 32, 29, 27, 24, 19, 14

3. Apply Conditions & Arrange: Systematically place individuals using the given conditions. Crucial deductions involve combining multiple facts. For example, conditions like "Z's age is an odd number," "Z is not the oldest," and "Z is older than both K and X" collectively imply that Z's age must be 29 (born in 1992). This kind of elimination and inference is key to narrowing down possibilities and precisely placing individuals within the chronological structure.

Question: What is the age of T?

Answer: T is 27 years old.

Year-Based Puzzle (Problem 2)

This puzzle involves arranging seven individuals based on their birth years, calculating ages from a base year (2022), and applying conditions that include age sums and differences.

Solving Steps:

1. Arrange Years: List the provided birth years chronologically.

• 1974, 1983, 1989, 1992, 1999, 2010, 2013

2. Calculate Ages: Compute each person's age by subtracting their birth year from the base year (2022).

• Ages: 48, 39, 33, 30, 23, 12, 9

3. Apply Conditions & Arrange: This puzzle emphasizes using conditions involving sums and differences of ages. For instance, knowing "E was born in an even year" and that "the sum of the ages of E and B is 42" helps identify potential E-B pairs. If E is 30 (born in 1992), B's age is 12 (42-30). If E is 12 (born in 2010), B's age is 30 (42-12). Further conditions, such as "the difference between the age of B and C is 3" and "the sum of the ages of C and A is 56," are then used to validate these pairs and systematically complete the arrangement by ensuring consistency across all facts.

Question: Whose age is 30?

Answer: B is 30 years old.

Grouping Puzzle: Year-Based Grouping

This is a grouping puzzle where ten players are to be grouped into three specific birth years (2015, 2017, 2022) based on seniority and other criteria. Unlike traditional year-based puzzles, multiple individuals can share the same birth year here.

Key Concept:

Instead of a linear arrangement where each person has a unique slot, individuals are categorized into predefined groups. Seniority is determined by being born in an earlier year (e.g., 2015 is Senior to 2017).

Groups:

• 2015 (Senior)

• 2017 (Middle)

• 2022 (Junior)

Conditions & Arrangement:

Deductions are made by eliminating possibilities and cross-referencing conditions. For example, if "M is NOT in 2015," M must be in either 2017 or 2022. If "M is Senior to N" is also given, and M is found to be in 2017, then N, being junior to M, must be in 2022. Similarly, a condition like "K is NOT born in a year which is a multiple of three" (thus excluding 2015 for K) combined with "K is Junior to Q" helps constrain Q and K's possible birth years through systematic elimination.

Question: How many people were born in 2017?

Answer: Four people were born in 2017.

Grouping Puzzle: Bank-Based Grouping

This puzzle requires grouping ten individuals into three banks (RBI, SBI, and PNB) based on working conditions, with specific constraints on group size.

Problem Constraint:

Each bank must have at least three but not more than four persons. Given 10 individuals across three banks, this implies a fixed distribution of 4, 3, 3 persons across the banks.

Conditions & Arrangement:

The solution involves using initial conditions to establish the group sizes and then systematically placing individuals.

1. "W works in RBI with only two other persons" immediately confirms that RBI has 3 persons. This then fixes the distribution for SBI and PNB as 4 and 3 (or 3 and 4).

2. "X and S are working together but not in PNB" implies X and S are in either RBI or SBI. Since RBI is limited to 3 (and W is one of them), X and S must be in SBI, which can accommodate 4 persons.

3. "V works in SBI with S" further populates SBI (now containing V, S, X).

4. "Y works in PNB" and "Not more than three persons are working in PNB" confirms PNB also has 3 persons, thereby definitively assigning SBI 4 persons.
   This sequential deduction, leveraging both positive and negative conditions, allows for the complete arrangement of individuals into their respective banks.

Question: How many persons are working with U?

Answer: Two persons are working with U.

Designation-Based Puzzle (Problem 1)

This type of puzzle requires arranging seven individuals according to a hierarchical designation structure, applying seniority and specific positional conditions.

Designation Hierarchy (Senior to Junior):

1. Chairman

2. MD (Managing Director)

3. HOD (Head of Department)

4. Senior Manager

5. Assistant Manager (AM)

6. Clerk

7. Trainee

Conditions & Arrangement:

The solution relies on directly mapping conditions to the hierarchy and using comparative statements for placement.

• A condition like "Only three persons are Senior to R" directly places R as the Senior Manager (the fourth position from the top).

• Subsequently, "R is just Junior to H" places H as HOD (the third position).

• Conditions involving relative positions, such as "The number of persons Senior to X is the same as the number of persons Junior to K," often require considering multiple cases. For example, if X is MD (1 person senior), then K must be Clerk (1 person junior). If X is AM (4 persons senior), then K must be MD (4 persons junior). Further conditions are then used to resolve such ambiguities, leading to the final unique arrangement.

Question: How many persons are Senior to W?

Answer: None. W is the Chairman.

Designation-Based Puzzle (Problem 2)

This puzzle involves arranging eight individuals according to an eight-level hierarchical designation structure, with more complex seniority and positional conditions.

Designation Hierarchy (Senior to Junior):

1. CEO (Chief Executive Officer)

2. COO (Chief Operating Officer)

3. CFO (Chief Financial Officer)

4. CAO (Chief Administrative Officer)

5. CIO (Chief Information Officer)

6. CTO (Chief Technology Officer)

7. CMO (Chief Marketing Officer)

8. CHRO (Chief Human Resources Officer)

Conditions & Arrangement:

This puzzle involves more intricate relative positioning and numerical comparisons to deduce placements.

• Conditions like "D is three posts Senior to E" combined with "Only two posts are between F and D" create a fixed relative sequence: F - - D - - E. This sequence spans seven positions, significantly constraining F's and E's possible roles within the eight-position hierarchy (e.g., F as CEO, D as CAO, E as CTO, or F as COO, D as CIO, E as CMO).

• The condition "Only either one or two persons are Junior to E" is critical for validating these possible sequences.

• Another key comparative condition, "The number of persons Junior to E is the same as the number of persons Senior to G," helps to confirm E's precise position and subsequently G's, demonstrating how numerical equivalences are used to narrow down possibilities. The remaining individuals are then placed by elimination.

Question: The number of persons Senior to D is the same as the number of persons Junior to H.

Answer: H.
