Triple Parameter: Floor + Color + Age

Triple Parameter puzzles involve arranging people on floors where each person has three distinct attributes (e.g., floor number, color preference, age). Clues may relate any of these attributes to each other. These complex puzzles test advanced multi-attribute matching and systematic deduction skills.

Introduction to Triple Parameter: Floor + Color + Age

Triple Parameter puzzles involve arranging people on floors where each person has three distinct attributes (e.g., floor number, color preference, age). Clues may relate any of these attributes to each other. These complex puzzles test advanced multi-attribute matching and systematic deduction skills.

Prerequisites

Basic floor arrangement skills Multi-attribute matching concepts Process of elimination Constraint satisfaction with multiple dimensions
Why This Matters: Triple Parameter puzzles appear in 1-2 questions in Banking PO mains and CAT exams. They test advanced multi-attribute reasoning.

How to Solve Triple Parameter: Floor + Color + Age Problems

1

Step 1: Create a table with floors as rows and attributes as columns (Floor, Color, Age)

2

Step 2: Place directly given assignments (e.g., 'Person with Red color lives on floor 3')

3

Step 3: Apply relational clues (e.g., 'The Blue person lives above the 25-year-old')

4

Step 4: Use elimination to match each floor with a color and age

5

Step 5: Ensure each attribute value is used exactly once per attribute type

6

Step 6: Cross-reference between attributes to resolve ambiguities

7

Step 7: Answer the specific question about a person's attribute

Pro Strategy: Create a table with floors as rows. Use direct assignments to fill known values. Use relational clues to establish ordering. Use elimination to match remaining colors and ages. Each color and age appears exactly once.

Example Problem

Example: 4 floors (1-4), 4 persons with distinct colors (Red, Blue, Green, Yellow) and ages (20,25,30,35). Red person lives on floor 2. Blue person lives above Green. The 30-year-old lives immediately below the 35-year-old. Yellow person is not 25. Find the age of the Blue person. Solution: Step 1: Table: Floor | Color | Age Step 2: Red at floor 2 Step 3: Blue above Green → floor(Blue) > floor(Green) Step 4: 30 immediately below 35 → consecutive with 30 below 35 Step 5: Yellow not 25 Step 6: Eliminate possibilities to assign colors and ages Answer: Blue person's age determined

Pro Tips & Tricks

  • Create a table: Floor | Person/Name | Color | Age
  • If a person is not named, track by floor number
  • Each attribute value (color, age) is unique across all persons
  • Use positive clues to link attributes (e.g., 'Red person lives on floor 2' links color to floor)
  • Use comparative clues to order attributes (e.g., 'X lives above Y')
  • Start with the most restrictive clues (direct assignments)

Shortcut Methods to Solve Faster

Number of floors = number of persons = number of colors = number of ages
Direct assignment: floor(F) = value
Comparative: floor(X) > floor(Y) means X is above Y
Each attribute value appears exactly once per attribute type

Common Mistakes to Avoid

Forgetting that each attribute value is unique
Not updating the table after each deduction
Confusing attribute types (color vs age)
Applying relational clues in wrong direction
