ANS:D - 9

Structure of the Pattern:

1. Diagram Configuration:
   • The diagram consists of circles arranged in rows with a specific rule for number placement.
2. Pattern Calculation:
   • For each number in the top row, subtract 3 and place the result in the corresponding lower circle.

Explanation of the Pattern:

1. Identify the Top Row Numbers:
   • Look at the numbers in the top row of the diagram.
2. Apply the Calculation:
   • For each number in the top row, subtract 3.
3. Place the Result:
   • Put the resulting number in the corresponding circle in the lower row.

Step-by-Step Process:

1. Locate the Numbers in the Top Row:
   • Assume the numbers in the top row are a,b,c,a, b, c,a,b,c, etc.
2. Subtract 3 from Each Number:
   • Calculate the result for each number: Lower Circle Number=Top Row Number−3\text{Lower Circle Number} = \text{Top Row Number} - 3Lower Circle Number=Top Row Number−3
3. Place the Result in the Lower Circle:
   • Put the result in the corresponding lower circle.

Example Walkthrough:

Assume the top row has the following numbers:

• Top Row: 12, 15, 18

1. Calculate the Lower Circle Numbers:
   • For 12: Lower Circle Number=12−3=9\text{Lower Circle Number} = 12 - 3 = 9Lower Circle Number=12−3=9
   • For 15: Lower Circle Number=15−3=12\text{Lower Circle Number} = 15 - 3 = 12Lower Circle Number=15−3=12
   • For 18: Lower Circle Number=18−3=15\text{Lower Circle Number} = 18 - 3 = 15Lower Circle Number=18−3=15
2. Place the Results in the Lower Circles:
   • The lower circles corresponding to the top row numbers 12, 15, and 18 will have the numbers 9, 12, and 15, respectively.

Conclusion:

The answer "9" reflects the pattern where you subtract 3 from each number in the top row of the diagram and place the result in the corresponding lower circle. This consistent application of the subtraction rule creates the sequence of numbers in the lower circles.
