ANS:C - 3

The explanation describes a pattern where the sum of the digits in each row of a grid equals 10. Here's how to understand and apply this pattern:

Explanation of the Pattern:

1. Row Structure:
   • Each row contains several digits.
2. Sum Rule:
   • For each row, the sum of all the digits must equal 10.

Applying the Pattern:

To find or verify a number in the grid based on this pattern, follow these steps:

1. Identify the Digits:
   • Look at the digits in each row of the grid.
2. Calculate the Sum:
   • Add the digits in each row and ensure the total is 10.

Example:

Consider the following rows in a grid:

• Row 1: 4, 6
  • Sum: 4+6=104 + 6 = 104+6=10 (Matches the pattern)
• Row 2: 1, 2, 7
  • Sum: 1+2+7=101 + 2 + 7 = 101+2+7=10 (Matches the pattern)
• Row 3: 5, 5
  • Sum: 5+5=105 + 5 = 105+5=10 (Matches the pattern)

If each row in the grid adheres to this rule, then the number satisfying this pattern will fit the condition where the sum of the digits is always 10.

Conclusion:

The correct answer is 3 because it fits the pattern where the sum of the digits in each row equals 10. This consistent sum rule helps in verifying or constructing the grid.
