Element Count Oddity

Element Count Oddity problems present five figures where four have the same number of internal elements (dots, lines, small shapes) and one has a different count. You must count elements systematically to identify the outlier. These problems test attention to detail and quantitative comparison skills.

Introduction to Element Count Oddity

Element Count Oddity problems present five figures where four have the same number of internal elements (dots, lines, small shapes) and one has a different count. You must count elements systematically to identify the outlier. These problems test attention to detail and quantitative comparison skills.

Prerequisites

Basic counting skills Attention to detail Ability to count multiple elements in a figure Pattern recognition in quantities
Why This Matters: Element Count Oddity appears in 1-2 questions in SSC CGL and Banking PO exams. It tests counting skills and quantitative pattern recognition.

How to Solve Element Count Oddity Problems

1

Step 1: Count the number of elements in each figure

2

Step 2: Record the count for each figure

3

Step 3: Identify the count that appears most frequently

4

Step 4: The figure with a different count is the odd one out

5

Step 5: Verify that all other figures have the same count

Pro Strategy: Count elements systematically, from left to right or top to bottom. Double-check your count for each figure. The majority count defines the pattern.

Example Problem

Example: Four figures with 3 dots each, one figure with 2 dots. Which is odd? Solution: Step 1: Count dots: 3,3,3,3,2 Step 2: Most common count = 3 Step 3: Figure with 2 dots is different Answer: The figure with 2 dots is the odd one out

Pro Tips & Tricks

  • Count elements systematically (left to right, top to bottom)
  • Elements can be dots, lines, stars, or small shapes
  • Double-check counts for each figure
  • The outlier often has one more or one fewer element
  • Don't be distracted by element positions or arrangements

Shortcut Methods to Solve Faster

If most figures have N elements, the one with ≠N elements is odd
Count the first figure, then compare others quickly
Look for visual density differences

Common Mistakes to Avoid

Missing small or partially hidden elements
Counting elements of different types together when they follow separate patterns
Miscounting due to overlapping shapes
