The Correct Option is C
Solution and Explanation
We observe the pattern in the first matrix:
The sum of the numbers in each row equals the number in the last column: \( 3 + 4 + 20 = 27 \)
\( 2 + 1 + ? = 27 \)
Thus, \( ? = 27 - 2 - 1 = 24 \).
Now, observe the second matrix:
\( 7 + 8 + 52 = 67 \)
\( 6 + 5 + ? = 67 \)
Thus, \( ? = 67 - 6 - 5 = 56 \).
In the final matrix:
\( 12 + 13 + 11 = 36 \)
\( 10 + ? = 36 \), so \( ? = 36 - 10 = 26 \).
Thus, the missing number is 92. Answer: 92
