Question : Directions: Study the given pattern carefully and select the number that can replace the question mark (?) in it.
| 8 | 27 | 32 | 16 |
| 12 | 18 | 16 | 20 |
| 18 | 12 | ? | 25 |
Option 1: 8
Option 2: 14
Option 3: 10
Option 4: 12
Correct Answer: 8
Solution : Multiply row one with row three and determine the square root of the resultant, to get the required missing number of row two –
In column one: 8 × 18 = 144 = √144 = 12
In column two : 27 × 12 = 324 = √324 = 18
In column four : 16 × 25 = 400 = √400 = 20
Similarly, by following the same pattern for→32 × ? = 16
2
⇒ ? = 256/32⇒ ? = 8
So, the required missing number in the matrix is 8. Hence, the first option is correct.
