In the following question, select the related number from the given alternatives.

11 : 81 :: 12 : ?

1. 105
2. 102
3. 106
4. 100

Answer 1

Correct Answer - Option 4 : 100

Logic: Number : (Number - 2)²

11 : 81 → 11 : (11 - 2)² →  11 : 9² 

Similarly,

12: ? → 12 : (12 - 2)2 →  12 : 102 → 12 : 100

Hence, "100" is the correct answer
