Best answer
Correct Answer - Option 1 : 94

The logic follows here is :-

1) In the first column:

4
2
1
21

⇒ (4)² + (2)² + (1)² 

⇒ 16 + 4 + 1

⇒ = 21

So, the first column fourth row value is "21".

2) In the second column:

5
3
8
98

⇒ (5)² + (3)² + (8)²

⇒ 25 + 9 + 64

⇒ = 98

So, the second column fourth row value is "98".

3) In the second column:

6
7
3
?

⇒ (6)² + (7)² + (3)²

⇒ 36 + 49 + 9

⇒ = 94

So, the second column fourth row value is "94".

Hence, "94" is the correct answer.
