Correct Answer: 253


Solution : Add the square of row two with the multiplication of row one and row two, to get the third number –

In column one: 18 × 7 + 7 2 = 126 + 49 = 175
In column two: 21 × 15 + 15 2 = 315 + 225 = 540
Similarly, follow the same pattern in column three →
12 × 11 + 11 2 = 132 + 121 = 253

So, the required missing number in the matrix is 253. Hence, the third option is correct.
