Question

If the given matrix follows a certain rule row-wise or column-wise, then find the missing number.

• A. $112$
• B. $82$
• C. $14$
• D. $31$

Answer 1

Answer: (D)

$31$

In the given matrix, the pattern is following

$8^2+10=64+10=74$

$4^2+15=16+15=31$

${12}^2+1=144+1=145$

Hence, this is the answer.
