Option 3 : 100

Logic: in each column; √(middle element) = √(1^st element) + √(3^rd element)

In first column

⇒ √25 + √49 = 5 + 7 = 12 = √144

In second column

⇒ √16 + √36 = 4 + 6 = 10 = √100

In third column

⇒ √64 + √? = 8 + √? = √324 = 18

⇒ √? = 18 - 8 = 10

⇒ ? = 10² = 100

Hence, “100” is correct answer.
