Question : Directions: Study the given pattern carefully and select the number that can replace the question mark (?) in it.
Option 1: 60
Option 2: 50
Option 3: 55
Option 4: 75
Correct Answer: 55
Solution : Given:
The pattern can be observed running vertically down the columns. Column 1: (9) 2 – (6) 2 = 81 – 36 = 45 Column 3: (12) 2 – (8) 2 = 144 – 64 = 80 Column 2: (8) 2 – (3) 2 = 64 – 9 = 55
So, 55 is the missing number. Hence, the third option is correct.
