Question : Directions: Study the given pattern carefully and select the number that can replace the question mark (?) in it.
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.
