Correct Answer: 16


Solution : Given:

25 36 64
81 9 4
16 49 100
18 ? 20

The pattern can be observed running vertically down the columns.
Column 1: (√25) + (√81) + (√16) = 5 + 9 + 4 = 18
Column 2: (√36) + (√9) + (√49) = 6 + 3 + 7 = 16
Column 3: (√64) + (√4) + (√100) = 8 + 2 + 10 = 20

So, 16 is the missing number. Hence, the third option is correct.
