4 : 18 :: 12 : ? :: 7 : 51
Option 1: 146
Option 2: 142
Option 3: 148
Option 4: 144
Correct Answer: 146
Solution :
Given:
4 : 18 :: 12 : ? :: 7 : 51
Add 2 to the square of the first number, to get the second number –
Like, 4 : 18→(4)
2
+ 2 = 16 + 2 = 18
And, 7 : 51→(7)
2
+ 2 = 49 + 2 = 51
Similarly, follow the same pattern for 12 : ?→(12)
2
+ 2 = 144 + 2 = 146
So, 146 is related to 12. Hence, the first option is correct.
