Question

Find out the missing item from the following: 
$ \begin{array}{|c|c|c|} \hline 15 & 6 & 4 \\ \hline 6 & 8 & 7 \\ \hline 2 & 6 & ? \\ \hline \end{array} $

• A. 8
• B. 9
• C. 10
• D. 11

Hint:

Look for patterns in the sum or difference between numbers in rows or columns to solve such puzzles.

Answer 1

The Correct Option is B

In this problem, the pattern for the sum of the numbers in each row is consistent. 
- In the first row: \( 15 + 6 + 4 = 25 \) - In the second row: \( 6 + 8 + 7 = 21 \) 
- In the third row: \( 2 + 6 + 9 = 17 \) 
The pattern seems to follow the sum of numbers decreasing as we go down the rows. 
The missing number in the last column should complete the sum of the third row. 
Hence, \( 2 + 6 + 9 = 17 \). 
The missing number must be \( 9 \) to balance the row.
