Question : Directions: In the following question, select the number that can be placed at the sign of the question mark (?) from the given alternatives.
| 1 | 7 | 2 |
| 8 | 6 | 4 |
| 9 | 2 | 5 |
| 4 | 7 | ? |
Option 1: 9
Option 2: 10
Option 3: 11
Option 4: 12
Correct Answer: 11
Solution : Here, the sum of all the numbers in each column is 22.
In column one: 1 + 8 + 9 + 4 = 22
In column two: 7 + 6 + 2 + 7 = 22
Similarly, follow the same pattern in the third column: 2 + 4 + 5 + ? = 22⇒? = 22 – 11 = 11
So, the missing number is 11. Hence, the third option is correct.
