Non-Verbal Reasoning by Dr. R S Aggarwal- Analytical Reasoning – Short Trick to Finding no of lines

Certainly! Here’s a concise guide to a short trick for quickly determining the number of lines in non-verbal reasoning figures, as inspired by Dr. R.S. Aggarwal’s “A Modern Approach to Verbal & Non-Verbal Reasoning.”

Short Trick to Count Lines in Non-Verbal Reasoning Figures

When faced with complex geometric figures, especially those involving overlapping lines, it’s essential to have a systematic approach to count the total number of lines accurately.

Step-by-Step Strategy:

1. Identify Basic Shapes:
   • Break down the complex figure into recognizable basic shapes such as triangles, squares, rectangles, etc.
2. Count Lines in Each Shape:
   • Determine the number of lines forming each basic shape. For instance, a triangle has 3 lines, a square has 4, and so on.
3. Look for Overlapping Lines:
   • In figures where shapes overlap, some lines may be shared between shapes. Identify these shared lines to avoid double-counting.
4. Apply the Formula:
   • Use the formula:

     Total Lines = (Sum of lines in all individual shapes) - (Number of overlapping lines)
     

5. Cross-Verification:
   • After counting, cross-verify by tracing each line in the figure to ensure none are missed or counted multiple times.

Example:

Imagine a figure composed of two overlapping squares (like a Star of David).

• Step 1: Each square has 4 lines.
• Step 2: Total lines without considering overlap: 4 (first square) + 4 (second square) = 8 lines.
• Step 3: If the squares overlap such that they share 2 lines, subtract these overlapping lines once: 8 – 2 = 6 lines.
• Step 4: Thus, the figure has 6 distinct lines.

Additional Tips:

• Practice with Diverse Figures: Regular practice with various figures enhances the ability to quickly identify and count lines.
• Use Pencil Tracing: Lightly tracing lines with a pencil can help in visualizing and counting without missing any.
• Time Management: In competitive exams, allocate a specific amount of time per question to ensure timely completion.
