Correct Answer - Option 1 : 94
The logic follows here is :-
1) In the first column:
⇒ (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)² + (3)² + (8)²
⇒ 25 + 9 + 64
⇒ = 98
So, the second column fourth row value is "98".
3) In the second column:
⇒ (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.
