Question : Directions: In the following question, select the number that can be placed at the sign of the question mark (?) from the given alternatives.
| 3 | 4 | 2 |
| 1 | 6 | 5 |
| 4 | 2 | 3 |
| 20 | 14 | ? |
Option 1: 11
Option 2: 12
Option 3: 14
Option 4: 16
Correct Answer: 16
Solution : Square the number given in the third row and add the resultant with the sum of the number of the first and second rows to get the required missing number.
In the first column: 4
2
= 16 and 16 + 3 + 1 = 20
In the second column: 2
2
= 4 and 4 + 4 + 6 = 14
Similarly, follow the same pattern in the third column: 3
2
= 9 and 9 + 2 + 5 = 16
So, 16 is the missing number in the given matrix. Hence, the fourth option is correct.
