| 557 | 835 | 504 |

| 502 | 794 | ? |
Option 1: 596
Option 2: 552
Option 3: 558
Option 4: 544
Correct Answer: 558
Solution : Add row one and row two and divide the resultant by 2 to get the third row –
In column one: (557 + 447) ÷ 2 = 1004 ÷ 2 = 502
In column two: (835 + 753) ÷ 2 = 1588 ÷ 2 = 794
In column three : (504 + 612) ÷ 2 = 1116 ÷ 2 = 558
So, the required missing number in the matrix is 558. Hence, the third option is correct.
